The shirt cost 3 times $35.
The shoes cost 5 times $28.
3 * $35 = $105
5 * $28 = $140
$105 + $140 = $245
They cost $245.
The answer is that one of the numbers is 24 and the other is 50. Let's call the smaller number x, since the larger number is based on info provided for the smaller. So smaller number is x. The larger number is 3x-22, since it is 22 less than (subtraction) 3times (multiplication) the number, x. So add 2x (two times a smaller number) and 3x-22 together and set them equal to 98: 3x - 22 + 2x = 98. Simplify to get 5x = 98, divide to get that x = 24. Now put that x into the other equation for the larger number: 3(24)-22=50
The area of the new rug is
x² + 2x - 15
Since
A = l x w
The new rug is 3 in shorter than her old rug, so we divide the area by (x - 3)
(x² + 2x - 15) / (x - 3)
By factoring
(x - 3)(x + 5) / (x - 3)
Cancelling out terms
x + 5
