A) Original price : y =10.x
Cheaper brand : y = 7x

Answer:11 is vertical
12 is adjacent
13 is vertical
Step-by-step explanation:
3s + h = $47
7s + 2h= $107
3s + h =$47
3s - 3s + h = $47 -3s
h = $47 - 3s
7s + 2($47 - 3s) = $107
7s + 94 -6s = 107
s + 94 = 107
s +94 -94 = 107- 94
s = 13
3(13) + h = $47
39 + h =$47
39 -39 + h= $47-39
h = 8
Check
7s + 2h= $107
7(13) + 2(8)= $107
91 + 16= 107
107 = 107
She earns $13 per suit sold and $8 per pair of shoes sold.
Calculate the area of the base which is 8.5 * 4 = 34. Next Multiply that by the height of 14 to get 14 * 34 = 476
