Question

Dan wants to save $100 in the next 2 months.  He knows that in the second month he will be able to save $20 more than during the first month.  How much does he save each month?

Answer 1

x= the amount he saves during the 1st month

x+20= the amount he saves during the second month

 

x + x+20 = 100

2x = 80

 x=40

$40 the first month

$60 the second month
