Sam began with $45 in his bank account. He then saved $15 a week until he had $210 in his account. How many weeks did Sam save $15?

Sam had to save $15 for 11 weeks

Step-by-step explanation:

$45+$15w=$210

Subtract $45 on both sides:

$45-$45+$15w=$210-$45

$15w=$165

Divide 15 on both sides:

15/15w=165/15

w=11

6.9

step-by-step explanation:

simple math really

6 1/2 times 0.6 = 3.9

but if you are just doing 6 and not 6 1/2 then the answer is 3.6
