Question

3) Sara goes to university in the city with $900 in her savings account. She needs to buy a tablet for $200and every 2 weeks, she withdraws $60 from her savings account for groceries. How many times canshe withdraw money for food until there is less than $300 in her account?

Answer 1

Given:

Sara has $900 in her savings account

She buys a tablet for $200.

Now the remaining amount is $900-$200=$700.

Let x be the number of times she withdraws $60.

she withdraws money for food until there is less than $300

`60x=700-300`

`60x=400`

Dividing both sides by 60, we get

`(60x)/(60)=(400)/(60)`
`x=6.67`

Round off, we get x=7.

Sara can withdraw 7 times for food.
