Question

Cate wants to buy calzones and sodas for her friends she finds that when she buys two calzones and three sodas she pays $13 when she buys three calzones and two sodas she pays $17 the prices for a calzone c and a soda s can be found with the following system of equations 2c+3s=13 write the prices for a calzone and for soda as an ordered pair (c,s) 3c+2s=17 Help!!

Answer 1

the answer is 5,1

Explanation:

in the demos activity, if u type to two equations in you should see two different colored lines on the graph. find the intersecting point using the two line from the equations you type in and the intersecting point is the answer. for calzones, it's 5, and for sodas, it's 1.

see the answer also at M a t h W a y.

Answer 2

The prices for a calzone and for soda as an ordered pair (c,s) is (5,1)

Explanation:

Let c be the prize of calazone

Let s be the prize of soda

She buys two calzones and three sodas she pays $13

So, 2c+3s=13

She buys three calzones and two sodas she pays $17

So, 3c+2s=17

Plot the equations on graph

2c+3s=13 --- Green

3c+2s=17 --- Blue

Intersection point will give the intersection point

So,(c,s)=(5,1)

So, Option c is correct

The prices for a calzone and for soda as an ordered pair (c,s) is (5,1)
