Question 1
Julio takes his brother to a music store. The music store sells CDs for \$15
each. If Julio and his brother have \$50, how many CDs can they buy?
\$15 = rate; \$50 = initial amount
\$15 = initial amount; \$50 = rate
\$15 = rate; -\$50 = initial amount
\$15 = initial amount; -\$50 = rate

Write an equation for the amount of debt she will still have, y, after x hours.
y = 25x + 16,500
y = 25x - 16,500
y = 16,500x - 25
y = 25x
