Question

Toni and Marcy partnered together in running laps around a track to raise money for the Children's Hospital's playroom. Toni raised $20 plus $0.80 per lap that he ran. Marcy raised $15 plus $0.85 per lap that she ran. Toni swam 1 1/4 times as many laps as Marcy swam. Together they raised a total of $257.00.

Answer 1

x represent the number of laps Marcy swam, 1 1/4x represent the number of times Toni swam.

20 + 0.80(1 1/4x) + 15 + 0.85x = 257
20 + x + 15 + 0.85x = 257
1.85x + 35 = 257

Required equation is 1.85x + 35 = 257
