Use an inequality to graph the possible number of weeks that person will need in order to reach their goal.

Accepted Solution

A:
Kate: 1250 ≥ 525+25x

25x ≥1250 -525

25x ≥ 725

x ≥  725 / 25

x≥ 29 weeks

Rebecca: 1350 ≥ 510 + 30x

30x ≥ 1350 - 510

30x≥ 840

x≥ 840 / 30

x≥28 weeks
Katie needs 1 more week than Rebecca
