Question

The amount of money raised at a school fundraiser is directly proportional to the number of people who attend. Last year the amount of money raised for 100 attendees was $2500. How much money will be raised is 875 people attend this year?

Answer 1

Amount of money raised for 875 people=A=$21,875

Explanation:

This can be expression in the equation, A=k.N;

Where;

A=Amount of money raised=$2500

k=Constant of proportionality(Amount of money per attendee)

N=Number of attendees=100

Replacing in the expression;

Amount of money raised=K×Number of people who attend

2500=K×100

K=(2500/100)=25

Amount of money per attendee=K=$25 per attendee

How much money was raised for 875 people?

Using the expression, A=k.N

where;

Number of people (N)=875

k=25

Replacing;

A=(25×875)=$21,875

Amount of money raised for 875 people=A=$21,875
