You can buy 0, 1, 2,and 3 cds. You have to do 80 minus 20 to find the amount of money that you can spend on the cds. You get 60. Then divide 60 by 18 because 60 is the amount of money you have and 18 is the cost for each cd. You get 3.3333333333333 and an infinite more 3s. Round it down to 3 meaning that you can buy up to 3 cds and you could buy 0, 1, 2, and 3 cds.
As per linear equation, the possible number of CDs Felicia could buy from the store is up to 3.
What is a linear equation?
A linear equation represents an equation that has one or multiple variables with the highest power of the variable is 1.
Given, Felicia had $80 when she went to a music store.
The store charges $18 for each CD.
She needs to have no less than $20 in her wallet.
Let, Felicia bought 'x' number of CD.
Therefore, $(80 - 18x) ≥ $20
⇒ 18x ≤ 60
⇒ x ≤ 60/18
⇒ x ≤ 3.33
Therefore, the maximum number of CD Felica bought from the store is 3.
