Question

Tim's phone service charges $22.22 plus an additional $0.23 for each text message sent per month. If Tim's phone bill was $27.97, which equation could be used to find how many text messages, x, Tim sent last month?

A.
$0.23x + $22.22 = $27.97

B.
$22.22x + $0.23 = $27.97

C.
$22.22x - $0.23 = $27.97

D.
$0.23x - $22.22 = $27.97

Answer 1

A

Explanation:

Service charge is a fixed charge. To find the charge for x text messages, multiply 0.23 by x

Charge applied for x messages = 0.23*x

= 0.23x

fixed charge + charge for 'x' text messages = total charge

22.22 + 0.23x = 27.97
