Kelly earns 20% more than Scott, and together they earn $1210.00 per week. How much does Kelly earn per week?

20/100x1210

2x121

=242

therefore Kelly earns

242+1210

=$1452

$726

Step-by-step explanation:

Divide 1210 by 2.

1210/ 2 = 605

Distribute .20% more to Kelly's name and subtract .20% from Scott's name.

605 x .20 = 121

Kelly: 605 + 121= 726

Scott: 605- 121 = 484

Recheck if both numbers add up to 1210.

726 + 484 = 1210

Check to see if Kelly earns 20% more than Scott. By doing this we will see what 20% of 1210 is.

1210 x .20= 242

Subtract Scott's pay from Kelly's pay.

726- 484= 242

There is a 20% difference in their pay, therefore Kelly is being paid $726 per week.

step-by-step explanation:

hope this .

option a is correct.

step-by-step explanation:

scale factor: it is used to find proportional measurements.

proportions means having the same ratio.

scale factor is the ratio of the model measurement to the actual measurement in a simplest form.

or we can say that the ratio of any two corresponding lengths in two similar geometric figures

if the scale factor is more than 1, then it is an enlargement,

if the scale factor less than 1, then it is a reduction.

given the two geometric figure:

by definition of proportions, we have
