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
