Garland put 26 + 3 dollars in the bank in the first week. The
following week he doubled the first
week's savings and put that amount in
the bank. The next week he doubled
what was in the bank and put that
amount in the bank. If he now has $477
in the bank, how much did he put in
the bank the first week?

Step-by-step explanation:

week one= 2b +3

week two = 2(2b+3) = 4b+6

week three = 4(2b+3) = 8b+12, therefore

477 = 2b+3 +4b+6 +8b+12

477 = 14b +21

14b = 456

b = 32.57

week one he put in 2*32.57 + 3 = $68.14

check this

68.14+(2×68.14)+(4×68.14) = $476.98 is approx $477
