Dorian buys 2 pounds of almonds for $21.98 and 3 pounds of dried apricots for $26.25. Which is less expensive per pound? How much is less expensive?

Answers

Dried apricots are $2.24 per pound less expensive.

Step-by-step explanation:

Apricots are less expensive by $2.24 per pound.

Step-by-step explanation:

The cost of 2 pound of almonds for = $21.98

The cost of 1 pound of almonds =

                                                    = $10.99

The cost of 3 pounds dried apricots for = $26.25

The cost of 1 pound dried apricots =

                                                         = $8.75

Difference in cost per pound = 10.99 - 8.75

                                                 = $2.24

3lbs of apricot for $26.25 because they are 2.24 less that 2lbs of almonds for $21.98

Complete the net worth statement by determining the total assets and total liabilities. What is the net worth?
A) $200
B) $2,000
C) $10,700
D) $12,700

Answers

Answer:

B

Step-by-step explanation:

1. Add all of the assets($12,700) and all of the liabilities($10,700).

2. Subtract the liabilities from the assets.

The total net worth of the given assets and liabilities is $2000.

What is the net worth?

The net worth is the difference between the total assets and the total liabilities.

net worth = assets - total liabilities

The total of all the assets is $12,700 and the total of all of the liabilities is $10,700.

net worth = assets - total liabilities

net worth = $12,700 - $10,700

                =  $2000

Therefore, the total net worth of the given assets and liabilities is $2000.

Steven and Anna start running from the school. Steven starts 15 seconds before Anna and runs at a rate of 3 feet per second. Anna runs at a rate of 4 feet per second. After how many seconds would Anna catch up with Steven?

Answers

Answer:

11.25 feet

Step-by-step explanation:

3*15=45;

45/4=11.25

Answer: After 15 seconds, Anna will catch up with Steven.

Step-by-step explanation: Set up the equation so that their distances will be equal at some time, x.

Distance = speed × time

3x + 15 = 4x . Subtract 3x from both sides

15 = 4x-3x

15 = x  The time is 15 seconds.

At that point their distances will be equal at 60 feet.

3(15) + 15 = 60

4(15) = 60

b. The school spent $500 on calculators. How many did the school buy?

Answers

Answer:

A. 31.25x=$500

B. 16

Step-by-step explanation:

a)

The amount paid for x calculators is 31.25x.

b)

The number of calculators the school bought is 16.

What is an expression?

An expression is a way of writing a statement with more than two variables or numbers with operations such as addition, subtraction, multiplication, and division.

Example: 2 + 3x + 4y = 7 is an expression.

We have,

Cost of each calculator = $31.25

Cost of x calculators.

= 31.25x

Now,

The total cost of the calculators = $500.

The number of calculators bought.

= 500/31.25

= 16

Thus,

The cost of x calculators is 31.25x.

The number of calculators bought is 16.
