A.
M = 3.5h; about 4 hours


B.
M = 3.5h; about 12 hours


C.
h = 3.5M; 53 hours

Answer 1

A.

M = 3.5h; about 4 hours

Explanation:

M(earned money)=h(worked hours)*$3.50

M = money earned

H = hours spent baby sitting

Basically, M = $3.50 x H, or M=$3.50H

So, if H = 6 then, 6 x $3.50 = $21 so M = $21

M= 3.50H

you would multiply the number of hours by 3.50 and that would be the total about of money earned.
