Question

The amount that Diego earns at his part time job is proportional to the number of hours he works. he earns $10 per hour.

a. writes an equation in the form y = KX to describe this situation, where x represents the hours he works, and y represents the dollars he earns

Answer 1

• He earns per hour=10

Let hours be x

• He earns in 1 h=10x=10(1)=10
• He earns in 2h=10(2)=20

Hence the expression is

`\\ \sf\longmapsto y=10x`

Answer 2

• y = 10x

Explanation:

• Number of hours worked = x
• Total earning = y
• Earning per hour = $10

The proportional relationship formula for this situation is:

• y = 10x

We just substituted k with 10 to represent hourly earning.
