PLEASE HELP! Kelly earns 20% more than Scott, and together they earn $1210.00 per week. How much does Kelly earn per week? Round to the nearest cent if needed.

Kelly earns $660 in a week.

Step-by-step explanation:

Let x represent the amount that Scott earns in a week.

Kelly earns 20% more than Scott

The value of 20% of x is

20/100 × x = 0.2 × x = 0.2x

This means that the amount that Kelly earns in a week is expressed as

x + 0.2x = 1.2x

Together, Kelly and Scott earn $1210.00 per week. This means that

x + 1.2x = 1210

2.2x = 1210

x = 1210/2.2

x = $550

The amount that Kelly earns per week would be

1.2x = 1.2 × 550

= $660
