Part A:
y=mx+b
621=83(7)+b
Part B:
621=83(7)+b
621=581+b
621-581=b
b=40
Insurance cost is 40$
Let x represent milk chocolate bar
y represent creamy nougat bars
3x+4y=4.25
6x+4y=6.5
6x+4y=6.5
-
3x+4y=4.25
=
3x=2.25
x=$0.75
y=$0.5. As a result, one milk chocolate bar costs $0.75 and one creamy nougat bar costs $0.5. Hope it help!
