So firstly, let's figure out the expression for a singular goody bag. Since there's 2 of each item, a single goody bag is going to be [tex] (1.07*2+0.85*2+2.12*2) [/tex]
Now since we have 7 friends who are all getting 1 goody bag, multiply the cost of the goody bag by 7, and our expression is [tex] 7(1.07*2+0.85*2+2.12*2) [/tex] . Now we can solve it from there.
Firstly, solve the multiplication inside the parentheses: [tex] 7(2.14+1.7+4.24) [/tex]
Now add up what's inside the parentheses: [tex] 7(8.08) [/tex]
Lastly, multiply and your answer will be $56.56
