Question

Problem 3

Answer 1

Answer: Problem 3: 20 laps per day,

Inequality: x >=20 per day

Problem 4: minimum of 8 employees

Step-by-step explanation:

Given that the goal is 600 laps in a month

And a month contains 30days, to achieve 600 laps, we divide 600 laps by 30 days

= 600/30= 20

Reem needs to swim a minimum of 20 laps per day to achieve her goal.

Inequality: x should be greater than or equal to 20 laps daily.

x >= 20

Problem 4:

Given that each employee can paint 85square feet per hour

The building has 1360 square feet and to be completed in two hours

Number of employees to complete the job in one hourwill be 1360/85 = 16

If 16 employees will complete 1360 per hour, then 8 employees will complete the work in 2 hours.
