Question

A new gaming chair costs $239.87. You have already saved $118.37 and earn $40.50 each week babysitting. Write and solve an equation to determine how many weeks, w, you must babysit to earn enough money to buy the new gaming chair.

40.5w + 118.37 = 239.87; w = 3
40.5w − 118.37 = 239.87; w = 9
40.5w − 239.87 = 118.37; w = 9
40.5 + 118.37w = 239.87; w = 3

Answer 1

40.5w + 118.37= 239.87; w=3

Explanation:

Answer 2

40.5w + 118.37= 239.87; w=3
