Tcecarenko [31]

Answer: the expression that represents the total number of items that have been collected is

7d + 12

Step-by-step explanation:

You are collecting pairs of socks and toothbrushes for a local charity.

Total number of pairs of socks that you would have collected after d days is (4d+5)

Total number of toothbrushes that you would have collected after d days is (3d+7). Therefore, the expression that represents the total number of items that have been collected after d days would be

4d + 5 + 3d + 7

= 4d + 3d + 5 + 7

Kasey and her sister both sold cookie dough. Her sister sold three times as many tubs of cookie dough. If they sold a total of 8

Rufina [12.5K]

X= number of tubs Kasey sold
3x= number tubs sister sold

Add the number sold by Kasey and her sister to equal the total sold (88).

x + 3x= 88
combine like terms

4x= 88
divide both sides by 4

x= 22 number tubs Kasey sold

Number Sold by Sister
3x= 3(22)= 66

CHECK:
x + 3x= 88
22 + 3(22)= 88
22 + 66= 88
88= 88

ANSWER: Kasey sold 22 tubs and her sister sold 66 tubs.

Hope this helps! :)
