Elsa is selling bracelets at craft shows to raise money for an animal shelter. She is also accepting additional cash donations. She plans to give 75% of the money from all bracelet sales and donations to the shelter. She will use the remaining money to buy more supplies. Bracelet sales and donations from the first craft show are represented by the expression 24n+32 , where n represents the amount Elsa charges for each bracelet. The second craft show sales and donations is represented by the expression 40n+56 . If Elsa charges $4 for each bracelet, how much money will she donate to the animal shelter?

Ответ:
2x + 5 = 5x - 22
3x = 27
x = 9.
2. Since M is the midpoint, then QM = MR.
2x + 5 = 5x - 1
3x = 6
x = 2
QR = QM + MR
QR = 2x + 5 + 5x - 1
QR = 7(2) + 4
QR = 18 units
