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
![(1.07*2+0.85*2+2.12*2)](https://img.qammunity.org/2019/formulas/mathematics/middle-school/uiv93rltav0wu2qo721lvl0vt26qdyko6r.png)
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
. Now we can solve it from there.
Firstly, solve the multiplication inside the parentheses:
![7(2.14+1.7+4.24)](https://img.qammunity.org/2019/formulas/mathematics/middle-school/93i2hepmw1xkyoye0y7uww4jjjr0zwe7oc.png)
Now add up what's inside the parentheses:
![7(8.08)](https://img.qammunity.org/2019/formulas/mathematics/middle-school/gmzn539hm4pcboox4c57ijx82fpk4m8pn6.png)
Lastly, multiply and your answer will be $56.56
