Math Algebraic equation

Question

Ava wants to save up money to buy an Ipad. She saves $20 each week. Write an equation that represents the relationship between the total amount of money Ava saves and the amount of weeks she saves for.

Answer 1

A=20w

A- cost of iPad

W- number of weeks

We know that Ava is saving 20 each(multiplication) week, w. We don't know the exact cost of the ipad so we represent A as the cost of the iPad.

Answer 2

A represents the amount of money

w represents the number of weeks

A = 20w
