Question

Tyrone likes to snack on his big bag of candy. He takes 8 pieces of candy from the bag each time he snacks. After eating 18 snacks, there are only 6 pieces of candy remaining in the bag.
The number c of pieces of candy remaining in the bag is a function of s, the number of snacks Tyrone eats.

Answer 1

c = 150 - 8s is the required function

Solution:

Given that,

Tyrone takes 8 pieces of candy from the bag each time he snacks

After eating 18 snacks, there are only 6 pieces of candy remaining in the bag

The number c of pieces of candy remaining in the bag is a function of s, the number of snacks Tyrone eats.

Therefore,

"c" is the number of pieces of candy remaining in the bag

"s" is the number of snacks Tyrone eats

Thus,

total number of candy in the bag = $18 \times 8 + 6 = 150$

Remaining candy in the bag = Total candy - candy he ate

c = 150 - 8s

Thus the function is found
