Ответ:
c) x = 16, y = 22
Step-by-step explanation:
Given data:
new release = $20
Classic = $8
Let x represent the number of new releases and Let y represent the number of classics
Total cost = 500
20X + 8Y = 500
Substituting answers in a) into the equation
20(8) + 8(45) = 520 (total than the maximum budget making this answer wrong)
Substituting answers in b) into the equation
20(10) + 8(22) = 376 (total is far less than the budgeted amount making this answer wrong)
Substituting answers in c) into the equation
20(16) + 8(22) = 496 (the total is approximately equal to the budgeted amount and the difference cant buy another disk making this the correct answer)
Substituting answers in d) into the equation
20(18) + 8(18) = 504 (total than the maximum budget making this answer wrong)
