I'm not sure what the 26 and 44 is there for but I'm guessing u want to multiply so in order to find the difference u got to multiply both sides the subtract so the answer would be 352
Try proportions. It can help since it's asking for the "cost". Hope this helps! :)
She enlarges by a scale factor of 1.2, so we can multiply this to all the measurements to find the sides of the enlarged triangle.
6 * 1.2 = 7.2
7 * 1.2 = 8.4
8 * 1.2 = 9.6
Now find the Area and Perimeter of the enlarged triangle.
A = 1/2bh
A = 1/2 * 9.6 * 8.4
A = 40.32
P = a + b + c
P = 7.2 + 7.2 + 9.6
P = 24
Susan would have to sell more than $69000 to make over 32,500 and less than $163000 to make under $41900
To calculate this you take the income she wants to make and subtract her salary
32500 - 25600 = 6900
you then multiply this by 10 to calculate the commission she needs to earn
6900 x 10 = 69000
Repeat this for the other side of the income scale.
