If I save $10 a week and double the amount each month. how much will I save the fourth month?

Question

I'm saving for a vacation. I'm saving $19 per week the first month. I will double that amount each month. How much will I be saving in the fourth month?

Answer 1

There are approx. 4 months in each month, therefore you will save $40 in the first month, $80 in the second, $160 in the third, & $320 in the fourth. If you want to find the weekly cost, just divide the monthly total saved by 4, because there is 4 weeks in a month.
