Question

Mikhael and Hema are planning the annual school fundraiser. They

Answer 1

Percent of earnings that go to school = 80%

Percent of earnings that was spent on the fundraiser cost = 20%

Last year earnings were= $4000

80% of 4000 went to school which is =

$\frac{80}{100}\times4000=3200$

20% of 4000 =$\frac{20}{100}\times4000=800$ went to costs.

a:

As given, this year, they want  $4,000 to go directly to the school.

So let the earnings this year be represented by = x

As, 80% of the earnings go to school, so 80% of x = 4000

$\frac{80}{100}*x=4000$

$80x=400000$

$x=5000$

Hence, this year their earnings should be $5000 so that 80% of it which is $4000 will go to school. And 20% which is $1000 will go to costs.

Or we can say last year they earned $4000, so this year they need to earn $1000 more.

b:

The total amount they need to earn this year is $5000.
