Answer:
x = 10
Step-by-step explanation:
-8(-3 + x) = -56
Distribute the -8 into the (-3 + x).
24 - 8x = -56
Subtract 24 from both sides.
-8x = -80
Divide both sides by -8.
x = 10.
Proof:
-8(-3 + x) = -56
Substitute variable.
-8(-3 + 10) = -56
Add inside parenthesis.
-8(7) = -56
Multiply.
-56 = -56
Let:
T = Total money they have
Dc = Dog collar
x = Number of bags of food

Let's solve the inequality:

This means that they can buy 12 bags of food at most.
Since they plan to buy 2 bags of food:

This means they can do it and have $ 11.5 to spare
P = 300 $; r = 0.06; t = 20; n = 1
A = P ( 1 + r/n)^n*t
= 300 ( 1 + 0.06) ²⁰
= 300 ( 1.06) ²⁰
= 962.14
Answer:
