Question

It is based on ratios

Answer 1

Gianna makes $18 per hour.

Explanation:

Given Gianna makes 90$ for 5 hours. That means she should make
`$ (90)/(5) $` $ = 18$ every hour.

Therefore we have:

a.

HOURS DOLLARS

1 18

2 36

3 54

4 72

5 90

6 108

7 126

b.

For the tabular column mark Hours on the x - axis and Dollars on the Y - axis. It can be plotted from the above table easily.

c.

If Gianna works for 8 hours she would have made 8 X 18 = 144$.

So, she will earn 144$ in 8 hours.

d.

To make 60$ she would have to work
`$ (60)/(18) $` hours = 3.33 hours.
