Question

Jenny wants to rent a truck for one day. She contacted two companies. Laguna’s Truck Rentals charges $20 plus $2 per mile. Salvatori’s Truck Rentals charges $3 per mile. After how many miles will the total cost for both companies be the same?

Answer 1

20+2x=3x subtract 2x from both sides
20=x after 20 miles the total cost for both companies will be the same

PROOF
20+2(20)=3(20)
20+40=60
60=60
