Question

The amount of money a performer earns is directly proportional to the number people attending

the performance. The performer earns $120 at a performance where 8 people attend.
How much money will the performer earn when 20 people attend a performance?
O $240
O $960
O $480
0 $300

Answer 1

You solve this kind of problem by using proportion
$ / people = 120 / 8 = x / 20
Cross multiply 120 x 20 = 2400
8x =2400
Divide 8 on both sides
x = 300
The performer will earn $300 when 20 people attend a performance.
