An Internet service offers internet access for $29.95 a month with a $15.75 initial charge for the hookup. If Gail spent a total of $195.45 on her total Internet bill, how many months did she pay for?

• 29.95 + 15.75m = 195.45

• 29.95m + 15.75 = 195.45

• (29.95 + 15.75)m = 195.45

• 29.95(m + 15.75) = 195.45

Kate has some dimes and $15.75 in quarters. If she has $27.95 total, How many dimes does she have?

• x + 15.75 = 27.95

• x + .25(15.75) = 27.95

• .10x + .25(15.75) = 27.95

• .10x + 15.75 = 27.95

Jerry is making 3 times the sum of his salary 20 years ago and $5000. He makes $81,000 now. How much did he make 20 years ago?

• 3x + 5,000 = 81,000

• 3(81,000) + 5,000 = x

• 3(x + 5,000) = 81,000

• 3(x + 20) + 5,000 = 81,000
