the college student spent 10 times as much on pizza as he did on laundry. if his laundry and pizza bills for the year totaled $495, how much did he spend on laundry
Let's represent the amount spent on laundry as "x".
Since the college student spent 10 times as much on pizza as he did on laundry, the amount spent on pizza would be 10x.
The total amount spent on laundry and pizza for the year is $495.
So the equation becomes:
x + 10x = $495
Combining like terms:
11x = $495
Dividing both sides of the equation by 11, we find:
x = $495 / 11 = $45
Therefore, the college student spent $45 on laundry.
