Final answer:
To find the total amount Jennifer spent on CDs and a CD player, multiply the cost of each CD by the number of CDs and add the cost of the CD player. Jennifer spent 90 in total.
Step-by-step explanation:
To find the total amount Jennifer spent, we need to multiply the cost of each CD by the number of CDs and add the cost of the CD player.
Let's define variables:
C = cost of a CD = 10
CDs = number of CDs = 4
P = cost of the CD player = 50
The equation to find the total amount is: Total Amount = (C imes CDs) + P
Plug in the values: Total Amount = (10 imes 4) + 50 = 40 + 50 = 90
Therefore, Jennifer spent a total of 90 on 4 CDs and a CD player.
