Jason deposits $5 into his savings account twice a week for 6 weeks. How much money will he have saved after 6 weeks?
gregori [183]

Answer:

$60

The equation is x(5(2))=s or x(10)=s when x = number of weeks

Step-by-step explanation:

For 6 weeks, all you have to do is plug in the 6 where the <em>x</em> is.

6(5(2)) = s

6(10) = s

60 = s

or

6(10) = s

60 = s
