Answer:
e= 10h+5
Step-by-step explanation:
h is no of hours
e is earnings
In this problem WP means what percent
20 = WP X 160
solve for WP, by dividing both sides by 160
and you get:
0.125 = WP
Change your decimal into a percent by multiplying by 100%
12.5% is your result.
I believe it's 3 because 4 times 3 equals 12 and 12 plus 8 equals 20!
4(3)+8=20
