<span>(3a^2 - 2a + 4) - (a^2 - 3a + 7) = (distribute the negative sign)
3a^2 - 2a +4 - a^2 + 3a - 7 = (add like terms)
2a^2 + a - 3
So, the answer is A!

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:

$8b+3.25p\leq 80$
