Sid is saving money to buy a scooter that costs $172. Sid has $18 andwill save $11 each week. How many weeks will it take Sid to saveenough money to buy the scooter?

Respuesta :

1) Gathering the data:

Scooter price: $172

Sid has $ 18

$11 w

2) We can solve this, by setting an equation. Since the problem says that Sid starts with $18 and earns $11 each week. As we don't know the number of weeks we can write:

11w+18=172 Subtract 18 from both sides

11w = 172 -18

11w = 154

w=14

So, if Sid carries on earning money that way He'll need 14 weeks to buy that scooter.
