Lin bought 1 pretzel from a snack cart that was marked $4.50. Why did she pay $4.83?
marshall27 [118]

Answer:

Sales tax

Step-by-step explanation:

You might have like 3% sales tax which is 3 percent of the original price added back onto it.

Sales tax is a tax that is put onto wanted and gourmet things, so chocolate isn't a needed item in life, so you have sales tax on it. On something like bread or meat, there might not be sales tax since you need food to survive. If something cost $100, and there is 3% sales tax, you will pay 103 dollars since 0.03 of 100 is 3.

X-3y=-24<br> 5x+8y=-5<br><br> this equation is substitution, need help :))
Leto [7]

Answer:

x=-9, y=5. (-9, 5).

Step-by-step explanation:

x-3y=-24

5x+8y=-5

--------------

x=-24+3y

5(-24+3y)+8y=-5

-120+15y+8y=-5

-120+23y=-5

23y=-5-(-120)

23y=-5+120

23y=115

y=115/23

y=5

x-3(5)=-24

x-15=-24

x=-24+15

x=-9
