Answer:
Step-by-step explanation:
Let number of chairs be x and number of desks be y
Total number of chairs and desks = 14
x + y = 14 --------------(i)
Total cost = $ 4870
125x + 515y = 4870 ------------(ii)
Multiply equation (i) by (-125).
(i)*(-125) -125x - 125y = -1750
(ii) <u>125x +515y = 4870</u> {Now add}
390y = 3120
y = 3120/390
y = 8
Plug in value of y in equation 1
x + 8 = 14
x = 14 - 8
x = 6
Number of chairs = 6
Number of desks = 8
