Mercedes receives a 25 dollars gift card for downloading music and wants to determine how many songs she can purchase. Each downloaded song costs 1 point 2 9 dollars Write and solve an inequality to determine m , the number of songs Mercedes can purchase. What is the approximate solution to the inequality? Round to the nearest whole number.
Answer
A
m is greater than or equal to 32
B
m is less than or equal to 19
C
m is less than or equal to 32
D
m is greater than or equal to 19
Explanation
Each song costs $1.29, so the total cost for m songs is 1.29m dollars. The $25 gift card gives the inequality 1.29m ≤ 25; dividing by 1.29 gives m ≤ about 19.38. Since Mercedes can purchase only a whole number of songs, she can buy at most 19, matching “m is less than or equal to 19.”
