Answer:
Wanda bought 3 CDs
Step-by-step explanation:
Assuming she tried to buy as many CDs as she could using her money, you would create an equation that is based on y=mx+b. y representing the total cost, m representing the cost of a single CD, x representing the number of CDs
The equation would be 47.16=15.72x and in order to find the total amount of CDs she can buy you would divide 47.16 by 15.72 to get 3, meaning she can buy a total of 3 CDs.
