Question1. A student will buy packs of AA batteries, packs of AAA batteries, and 1 pack of CC batteries. - The student will buy the same number of packs of AA and AAA batteries. - Each pack of AA batteries costs \10.−EachpackofAAAbatteriescosts$5.−Thepackof10. - Each pack of AAA batteries costs \$5. - The pack of \mathbf{C}batteriescosts batteries costs \18 18. - The student will spend a total of $108\$ 108.
Which equations can be used to determine xx, the number of packs of each of AA batteries and AAA batteries the student will buy? Select all that apply. A. 15x=9015 x=90 B. 23x=9823 x=98 C. 33x=10833 x=108 D. 10+(5+18)x=10810+(5+18) x=108 E. (10+5)x+18=108(10+5) x+18=108 F. (10+5+18)x=108\quad(10+5+18) x=108

Studdy Solution
Evaluate other options:
Option E: (10+5)x+18=108(10 + 5)x + 18 = 108 simplifies to 15x+18=10815x + 18 = 108, which is correct.
Option D: 10+(5+18)x=10810 + (5 + 18)x = 108 simplifies to 10+23x=10810 + 23x = 108, which is incorrect.
Option F: (10+5+18)x=108(10 + 5 + 18)x = 108 simplifies to 33x=10833x = 108, which is incorrect.
The correct equations are:
- Option A: 15x=90 15x = 90 - Option E: (10+5)x+18=108(10 + 5)x + 18 = 108
