Margarita [4]

Answer: She purchased 8 sports drinks,

Step-by-step explanation:

Let be "d" the number of sports drinks that April purchased and "p" the number of slices of pizza that April purchased.

Set up a System of equations:

\left \{ {{d=p+3} \atop {2.25p+1.25d=21.25}} \right.

In order to solve the System of equations you can use the Substitution Method:

1. Solve for "p" from the first equation:

d=p+3\\\\p=d-3

2. Substitute it into the second equation:

2.25(d-3)+1.25d=21.25

3. Finally, you must solve for "d" in order to find its value. You get that this is:

2.25(d-3)+1.25d=21.25\\\\2.25d-6.75+1.25d=21.25\\\\3.5d=21.25+6.75\\\\d=\frac{28}{3.5} \\\\d=8
