Question

Maurice bought 3 sodas and 4 candy bars for $10.17. Larry bought 2 sodas and 5 candy bars for $10.28. How much does a candy bar cost?

Answer 1

Answer:

The cost of a candy bar is $\ 1.5$

Step-by-step explanation:

Let

x----> the cost of a soda

y----> the cost of a candy bar

we know that

$3x+4y=10.17$-----> equation A

$2x+5y=10.28$-----> equation B

Solve the system of equations by graphing

Remember that the solution of the system of equations is the intersection point both graphs

The solution is the point $(1.39,1.5)$

see the attached figure

therefore

The cost of a soda is $\ 1.39$

The cost of a candy bar is $\ 1.5$
