Answer: Raina would make $208 for 13 hours of work at the same rate.
Explanation:
let "x" be the amount she would make for 13 hours of work. Then, you can set up the proportion:
(144 dollars / 9 hours) = (x dollars / 13 hours)
Now, cross-multiply and solve for x:
144 * 13 = 9 * x
x = (144 * 13) / 9
x = 1872 / 9
x = 208
