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
[tex]60x=700-300[/tex][tex]60x=400[/tex]Dividing both sides by 60, we get
[tex]\frac{60x}{60}=\frac{400}{60}[/tex][tex]x=6.67[/tex]Round off, we get x=7.
Sara can withdraw 7 times for food.
