Could anyone help me with this problem? Will mark brainiest! Please show all the work!
Semir, Sarah, and SungSo decided to raise money for a local homeless shelter by working in a local deli. The deli agreed to donate to the shelter a portion of the profits from each meal the three sold. Semir sold 3 times as many meals as Sarah. SungSo sold 2 more meals than Sarah.

a. Write an expression for the number of meals that each sold.
b. If Sarah sold 24 meals, how many meals did Semir and SungSo each sell?
c. How many meals did the three sell in all? Explain how to use the commutative property and the associative property of addition to make finding the sum easier.

Respuesta :

Answer:

(A) 24+72+48

(B) Sarah sold 24 meals and Samir sold 72 and SungSo sold 48.


(C) 144 is how many they sold in all.


Step-by-step explanation:

Samir sells 3 times as much as Sarah, so he sells 72. SungSo sells twice as much as Sarah so he sells 48. Sarah sells 24.

Using the Addition Standard Algorithm I calculated that they sold 144 deli meals.
a.) (going by last letter of their names for variables) r= 3h
h=r/3
o=h+2

b.) Semir sold 72 because 24x3=72
Sungso sold 26 because 24+2=26

c.) in total they sold 24+72+26 we can just add the two of them with fitting second digits that being 24+26 because it will equal 50 which is an easy number to work with then we can just do 50+72 which is 122
