Answer:
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
2.15
