Answer:
28
Step-by-step explanation:
3*7-7
3*7=21--7=28
c/7 = 6 1/7 ⇒ c = 43 ⇒ 43/7 = 6 1/7
Convert mixed fraction into a simple fraction
6 1/7 ⇒ (6 * 7 + 1)/7 = 43/7
c/7 = 43/7
proportionality:
a/b = c/d where ad = bc
a = c
b = 7
c = 43
d = 7
ad = bc ⇒ c7 = 7*43 ⇒ c7 = 301 ⇒ 7c/7 = 301/7 ⇒ c = 43

Assume that the number we are looking for is x.
We know that 55% of the number x is 22.
This means that:
55% of x = 22
55% * x = 22
0.55x = 22
<u>Now, we will simply solve for x as follows:</u>
0.55x = 22
x = </span>

x = 40

This is just basic math. If she works 40 hours and earns $8.50 per hour then she earns (40 x $8.50) and you then need to take 7.65 percent of that.
