Q:
# Brian wants to purchase a car wash "package" from his local car wash. He can either get unlimited car washes for a month for $35 with no additional charges. Or, he can buy a discount package, where he pays $22 for the month plus $1.50 per car wash. He wants to know how many car washes he would need to get in order to make the $35 deal a better choice. y=22x+1.5 Substitute 35 for x: y=22(35)+1.5; y=771.5, which means it would take 772car washes for the plans to be worth the same amount. y=1.5x+22 Substitute 35 for y: 35=1.5x+22; yβ8.7, which means at 9 car washes, the unlimited package at $35 would be cheaper. y=22x+1.5 Substitute 35 for y: 35=22x+1.5; yβ1.5, which means at 2 car washes, the unlimited package at $35 would be cheaper.y=1.5x+22 Substitute 35 for x: y=1.5(35)+22; x=74.5, which means the discount package is cheaper unless Brian gets 75 car washes.
