Question

Joshua orders pictures from a photographer. Each picture costs $12.75. A one-time shipping fee of $3.25 is added to the cost of the order. The total cost of Joshua’s order before tax is $79.75. How many pictures did Joshua order? Write an algebraic equation and solve.

Answer 1

Answer:

6 pictures

Step-by-step explanation:

Let x be the number of pictures that was bought

Let y be the total amount of money collected for the picture

y= 3.25+12.75

3.25+12.75x= 79.75

Therefore x can be calculated as follows

12.75x= 79.75-3.25

12.75x= 76.5

x= 76.5/12.75

= 6

Hence Joshua ordered 6 pictures
