Gnom [1K]

Answer:

Style A shoes sold : 152

Style B shoes sold : 88

Step-by-step explanation:

Let :

Style A shoes = x
Style B shoes = y

Forming equations :

x = 2y - 24
66.95x + 84.95y = 17,652

Substitute the value of x from 1 in 2.

66.95 (2y - 24) + 84.95y = 17,652
133.90y - 1606.80 + 84.95y = 17,652
218.85y = 19258.80
y = 88

Finding x :

x = 2(88) - 24
x = 176 - 24
x = 152

Solution :

Style A shoes sold : 152
Style B shoes sold : 88

olga2289 [7]

To find this out the easy way, add up all the numbers and an answer, then divide by 4.
59 + 64 + 68 + 63.67 = 254.67
254.67/4 = 63.66
A is not correct.
59 + 64 + 68 + 65.25 = 256.25
256.25/4 = 69.25
B is not quite correct.
59 + 64 + 68 + 75 = 266.
266/4 = 66.5
C is not correct.
59 + 64 + 68 + 89 = 280
280/4 = 70.
D.) is the correct answer.
