see explanation

step-by-step explanation:

part a

60x+50y=170

x- numbers of appointment

y- numbers of tips

part b

(75-10)x+35y=210

x- numbers of appointment

y- numbers of tips

part c

part b mentioned there is a rental fee need to pay (per appointment), you have to minus the fee to know the profit, on the other hand, part a didn't mention it.

b.) 160 miles on a 5 gallons car

step-by-step explanation:

240/10=24 miles/gallon

160/5=32 miles/gallon

30/1=30 miles/gallon

168/6= 28 miles/gallon

32 miles/gallon is the most amount, so this is the best.
