It is up and down. Solve for y then graph. A good online graphing calculator is Desmos. You just type in the equation once you have it equal to y just don't type in the y= part. See attachment.

you bought 5 chocolate bars and 8 blow pops for $23.25 your sister bought 2 chocolate bars and 13 blow pops for 21.55 how much d

kirza4 [7]

Answer:

$2.65

Step-by-step explanation:

Let chocolate bar = c and blow pops = b

As per given we have equations below:

5c + 8b = 23.25
2c + 13b = 21.55

13 times the first equation minus 8 times the second to eliminate b and find c:

13(5c + 8b) - 8(2c + 13b) = 13(23.25) - 8(21.55)
65c - 16c = 129.85
49c = 129.85
c = 129.85/49
c = 2.65

Each chocolate bar costs $2.65
