Katie received a $\$ 75$ gift card for her birthday. She decides to buy new music and movies for her electronic notebook with the gift card. Songs cost $\$ 1.29$ each and movies cost $\$ 14.99$ each.

If Katie buys $20$ songs, what is the greatest number of movies she can buy?

Solution

VerifiedStep 1

1 of 2If Katie buys 20 songs, then she will spend $\$1.29(20)=\$25.80$ on songs. Her gift card has $75 so she can spend$\$75-\$25.80=\$49.20$ on movies. Each movie is $14.99. Since$$\dfrac{49.20}{14.99}$\approx3.28$, she can buy at most 3 movies.
