SHOW ALL WORK

Answer 1

To find the distance traveled, we can use the formula: distance = speed × time.

Given that Caleb drives at a speed of 15 miles per hour for 3 hours, we can substitute these values into the formula:

distance = 15 miles/hour × 3 hours

Simplifying: distance = 45 miles

Therefore, Caleb travels 45 miles.

Answer 2

Choose the better buy. $12.95 for 3 pounds of nuts or $21.45 for 5 pounds of nuts..

Answer 3

To determine the better buy, we need to compare the prices per pound of nuts for each option.

Option 1:
$12.95 for 3 pounds of nuts

Price per pound = $12.95 / 3 pounds = $4.32 per pound

Option 2:
$21.45 for 5 pounds of nuts

Price per pound = $21.45 / 5 pounds = $4.29 per pound

Comparing the price per pound for both options, we can see that Option 2 is the better buy as it has a lower price per pound of nuts.

Answer 4

An employee’s hourly earnings is described at 10y=80x. What is the employee’s earning per hour?

Answer 5

To find the employee's earning per hour, we need to solve for y (earnings per hour) in the given equation:

10y = 80x

Divide both sides of the equation by 10:

y = 8x/10

Simplifying, y = 0.8x

Therefore, the employee's earning per hour is 0.8x.

Answer 6

The cost of watermelon is y = 3.45x. What is the cost for 1 watermelon?

y = 3.45x

y = 3.45(1)

Simplifying, y = 3.45

Therefore, the cost for 1 watermelon is $3.45.
