Skylar and her children went into a movie theater and will buy bags of popcorn and pretzels. Each bag of popcorn costs $8 and ea
Masja [62]

Answer:

8b+3.25p\leq 80

Step-by-step explanation:

Each bag of popcorn costs $8

Each pretzel costs $3.25.

  • The total cost of b bags of popcorn =$8*b=$8b
  • The total cost of p pretzels purchased =$3.25*p=$3.25p

Skylar has a total of $80 to spend on both items. This means that she can either spend less than or exactly $80.

i.e Total Cost \leq \$80

Skylar's Total cost on popcorns and pretzels =8b+3.25p

Therefore:

8b+3.25p\leq 80

Therefore, an inequality that would represent the possible values for the number of bags of popcorn purchased, b, and the number of pretzels purchased, p will be:

8b+3.25p\leq 80

Please help me branniest ❗️❗️

The slope of the line is five because upon factoring you recieve

y - 4 = 5x -10

which the slope is always the number connected to the x

Next plug in -2 or 2 to find if it is a point on the graph

upon plugging in 2

4 - 4 = 5(2) - 10

0 = 0

D would be the correct answer
