Jen makes $5.00 per hour more than Tiffany. If 12 times Jen's rate plus 3 times Tiffany's rate is $80.00, what is Jen's hourly age?

J = 5+T so T = J5
12 J + 3 T = 80
12 J + 3 (J5) = 80
12 J + 3 J 15 = 80
15 J = 95
J = 6 1/3
check
then T = 1 1/3
12(6 1/3) + 3( 1 1/3) = ?
72 + 4 + 3 + 1 = 80 sure enough
