Answer 1

350 = 3x + y

a) 3x + y ==> 3(60) + 160 = 180 + 160 = 340 This is NOT a way to earn enough money

b) 3x + y ==> 3(25) + 290 = 75 + 290 = 365 This IS a way to earn enough money

c) 3x + y ==> 3(30) + 260 = 90 + 260 = 350 This IS a way to earn enough money

d) 3x + y ==> 3(45) + 220 = 135 + 220 = 355 This IS a way to earn enough money
