Question

Nila decides to increase the rate she charges customers by $2 per hour. What equation should she now use to determine how much to charge her customers? Explain.

Answer 1

Explanation:

charges $2 per hour.

Let the total cost is C.

According to the question, Nila increase the rate by $2 per hour.

So, the total cost is

C = 2 x h

where, h is the number of hour.

So, C = 2 h

Answer 2

An equation:
`C = 2h`

Explanation:

Let h be the number of hours and C be the total number of charges.

As per the statement: Nila charges customers by $2 per hour.

"$2 per hour" means 2h

`\text{Total cost/charges} = \text{Fixed cost} + \text{Variable cost}`

Since, Fixed cost = 0

Variable cost = 2h

Then;

`C = 2h`

Therefore, an equation should she now use to determine how much to charge her customers is,
`C = 2h`
