Ten granola bars and 12 bottles of water cost $23. 5 granola bars and four bottles of water cost $10. how much do one granola bar in one bottle of water cost?

2.15

Step-by-step explanation:

Let g= cost of granola bars

b = cost of bottles of water

10g+12b =23

5g +4b = 10

I will solve this system by elimination

Multiply the second equation by -2

-2(5g +4b) = -2*10

-10g -8b = -20

Now we add this equation to the first equation to eliminate  g

-10g -8b = -20

10g+12b =23

   4b = 3

b = 3/4

A bottle of water = $.75

Now we need to find g

5g+4b =10

5g +4(.75) = 10

5g +3 = 10

Subtract 3 from each side

5g +3-3 = 10-3

5g =7

Divide by 5

5g/5=7/5

g = 7/5

g = 1 2/5

g =1.40

We want the cost of one bottle of water and 1 granola bar

1g + 1b

1.4+.75

where is the figure

y > 1/3x

y < = -x + 4

hope this : )
