Answer:
The cost of a box of crackers is $2.25.
Step-by-step explanation:
Let the cost of a containers of yogurt is $x and cost of a box of crackers is $y.
It is given that Mandy can buy 4 containers of yogurt and 3 boxes of crackers for $9.55.
[tex]4x+3y=9.55[/tex] .... (1)
She can buy 2 containers of yogurt and 2 boxes of crackers for $5.90.
[tex]2x+2y=5.90[/tex] .... (2)
On solving (1) and (2), using graphing calculator, we get
[tex]x=0.7[/tex]
[tex]y=2.25[/tex]
Therefore the cost of a box of crackers is $2.25.
