Question

Best Buy had a sale on iPads last week. 16GB iPad ‘s were on sale for $50 and 64GB iPad’s were on sale for $79. The receipts from the sale of 36 iPads totaled $2409. How many of each type of iPad were sold last week?

Answer 1

Answer:

So 15 of 16GB iPad and 21 of 64GB iPad was sold

Step-by-step explanation:

Let 16GB iPad= x

Let 64GB iPad= y

Total iPad= 36

Cost of x = $50

Cost of y = $79

Total sales amount= $2409

So let's form the equation.

X + Y = 36. ...... equation 1

50x + 79y = 2409..... equation 2

X + Y = 36

50x + 79y = 2409

X = 36-y

50(36-y) +79y =2409

1800- 50y +79y =2409

79y-59y= 2409-1800

29y= 609

Y= 609/29

Y= 21

X= 36-y

X= 36-21

X= 15

So 15 of 16GB iPad and 21 of 64GB iPad was sold
