Answer:
9x + 4y < 110
Step-by-step explanation:
This inequality works because its the cost of hammers ($9) multiplied by how many hammers are bought (x) plus the cost of wrenches ($4) multiplied by how many wrenches are bought (y). The total cost has to be less than 110.
Area of chalkboard = 4 feet x 6 feet = 24 square feet.
Total cost = 24 square feet x $7.21 per square foot = $173.04
Answer: $173.04

Answer:
6, 8, 10, and 12
Step-by-step explanation:
x + (x + 2) = (x + 4) + (x + 6) = 36
4x + 12 = 36
subtract 12 rom each side of the equation:
4x = 24
divide both sides by 4:
x = 6
x + 2 = 8
x + 4 + 10
x + 6 = 12
