50 plus 5 times 7
I you add 5 extra dollars each month for 7 months that would be $35 extra.
Also, watch your order of operations. Bob showed you 50 plus 5 x time.
You always do the multiplication first then the addition.

Oh! So it'll be:
5*7=35
35+50=85
Will save 85 dollars after the seventh month. Thanks.
