Question

2. Joey charges a flat fee of $10, plus $6 per hour for babysitting. Write an equation for the cost C, afterh hours of babysitting, then graph the equation.What do you think the slope and the y-intercept represent?How much does can Joey make if she babysit for 9 hours?

Answer 1

Given:

Joey charges a flat fee of $10, plus $6 per hour for babysitting.

We will write the equation for the cost (C) after (h) hours of babysitting.

So, the equation will be as follows:

`C=6h+10`

We will answer the following:

a) What do you think the slope and the y-intercept represent?

The answer will be:

The slope = the coefficient of h = 6

The y-intercept = the constant = 10

b) How much can Joey make if she babysits for 9 hours?

So, we will substitute h = 9 hours and find the corresponding value of C

`C=6*9+10=54+10=64`

So, the answer will be C = $64
