Question

Mrs. Salas drives 115 miles per week to give 9 voice lessons. She deducts the cost of eight gallons of gasoline at $2 per gallon from her profit. Mrs. Salas charges $35 for each voice lesson. What is her profit for one week?

Answer 1

the answer is $299. If you write an equation, it would be x=35(9)-16. $35 each for 9 lessons. And 2*8= 16.

x=35(9)-16

x=315-16

x=299
