A house painting company charges $376 plus $12 per hour. Another company $280 plus $15 per hour. A. how long is a job for which both companies will charge the same amount? B. What will the cost be?

For company a ($376 + $12 an hr) it would take 2 hours because 376+12 = 388+12 = 400 (376 + (12 x 2))

for company b, ($280 + $15) it would take 9 hours because 280 + 15 = 295 + 15 =

310 + 15 = 325 + 15 = 340 + 15 = 355 + 15 = 370 + 15 = 385 + 15 = 400 (280 + (15 x 8))

376 x (12 x 2)

376 x 24 = 400

280 x (15 x 8)

280 x 120 = 400

1) a = 2 hrs

b = 8 hrs

2) $400
