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
