Answer:

c. If x = 3. Substitute. f(3) = 40 - 3.75, which means if Aisha buys 3 pounds of birdseed, she saves $36.25.

c. If x = 18. Substitute. f(18) = 40 - 22.5, which means if Aisha buys 18 pounds of birdseed, she saves $17.50.

c. If x = 36. Substitute. f(36) = 40 - 45, which means if Aisha buys 36 pounds of birdseed, she needs $5.00 extra.

d. 8

Step-by-step explanation:

f(x) = 40 - 1.25x

c.

If x = 3. Substitute. f(3) = 40 - 3.75, which means if Aisha buys 3 pounds of birdseed, she saves $36.25.

If x = 18. Substitute. f(18) = 40 - 22.5, which means if Aisha buys 18 pounds of birdseed, she saves $17.50.

If x = 36. Substitute. f(36) = 40 - 45, which means if Aisha buys 36 pounds of birdseed, she needs $5.00 extra.

d.

x = x. f(x) = 40 - 1.25x = 30

1.25x = 10

Divide by 1.25 on both sides to isolate x.

x = 8

8 pounds is the answer.

Hope this helps :)

Have a nice day!
