A computer is advertised at $980 + tax + delivery. Tax is charged at 8%. (a) What is 8% of $980? (b) The total price is $1098.40 What is the charge for delivery?

(a)Tax = $78.40

(b)Delivery =$40

Step-by-step explanation:

A computer is advertised at $980 + tax + delivery.

(a) We want to determine 8% of $980

8%=

Therefore: 8% of $980 =0.08 X 980 =$78.40

The Tax on the Computer = $78.40

(b)The total price is $1098.40

Recall:

Total Price = $980 + tax + delivery

1098.40 = 980 + 78.4 + Delivery

1098.40 = 1058.40+ Delivery

Subtract 1058.40 from both sides

1098.40- 1058.40= 1058.40-1058.40+ Delivery

Charge for Delivery =$40

The answer would be 250 $
