1 answer:

6 0

A constant is a number, or a letter that represents a number that
never changes. From the time the problem starts until as long
as it lasts, its value is constant.

A variable is a letter that stands for a number that can change.

A coefficient is each of the items in a group of them that are all
multiplied together.

Example: 17x + 4y

That's an expression with two terms.
The terms are '17x' and '4yz'.

In the first term:
'17' is the numerical coefficient.
'x' is the literal coefficient.

In the second term:
'4' is the numerical coefficient.
'y' and 'z' are both literal coefficients.

<h3>c = 150 - 8s is the required function</h3>

<em><u>Solution:</u></em>

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

choli [55]

Let C be Clowns R Fun charge for b balloons and S be Singing Balloons charge.
C=6+1.25b and S=2+1.95b. C must be less than S.
6+1.25b<2+1.95b, 4<0.7b, b>4/0.7, b>40/7, b>5. So Mrs Travis needs to purchase more than 5 balloons.
