Question

kareem is putting money into a savings account . he starts with $650 in the savings account and each week he adds $70 . let S represent the total amount of money in the savings account ( in dollars ) and let W represent the number of weeks kareem has been adding money . write an equation relating S to W . then use this equation to find the total amount of money in the savings account after 19 weeks

Answer 1

• Let total amount of money=S
• W=Number of weeks

Principal=650

Per week addition=70

Equation

`\\ \sf\longmapsto S=650+70W`

Total money in 19weeks

`\\ \sf\longmapsto S=650+70(19)`

`\\ \sf\longmapsto S=650+1330`

`\\ \sf\longmapsto S=1980`
