A vendor sells pretzels and drinks at a corner stand. He charges $2.25 for a pretzel and $1.50 for a drink. One day, the vendor made a total of $463.50 by selling a total of 257 items.

Is this the right answer? $2.25p + $1.50d = $463.50

For this case, the first thing we must do is define variables:

p: number of pretzels

d: number of drinks

We now write the system of equations:

2.25p + 1.50d = 463.50

p + d = 257

Solving the system we have:

d = 153

p = 104

Answer:

104 pretzels

153 drinks
