creativ13 [48]

Answer:

$25.24

Step-by-step explanation:

If Tim earns $45.19 each month multiply by 3 which gives you $135.57 take $211.29 subtract $135.57, you get $75.72 which is the total amount that Tom needs to give. Divide that by 3 and get $25.64 which is the amount Tom needs in 3 months.

$45.19 x 3 = $135.57

$211.29 - $135.57 = $75.72

$75.72/3 = $25.24

so given the numbers we divide 787 by 3985 then multiply that by 100
