Let
x------------> the cost of one <span>slices of cheese pizza
y------------> the cost of one soda

we know that
3x+2y=8.75
2x+4y=8.50

using a graph tool
see the attached figure

the solution is
x=2.25
y=1
so
x+3y-----> 2.25+3*1------> 5.25

the answer is 
the option B) $5.25

When harry recipe on a 3” x 5” index card that he wants to enlarge to 15 inches long how wide will the enlargement be ??
Alexeev081 [22]
Hi there.

3x = 15 (length)

x = 5

Since we're multiplying the length by 5, we also multiply the width by 5.

5 • 5 = 25

The length of the enlargement will be 5".
