Find out the number of refills keith bought and write equation for it .
To prove
Let us assume that the number of refills be x .
a restaurant sells a coffee refill mug for $6.75.
Each refill costs $1.25
Last month keith spent $31.75 on a mug and refills .
Than the equation becomes
6.75 + 1.25 × x = 31.75
6.75 + 1.25x = 31.75
1.25x = 31.75 - 6.75
1.25x = 25
x = 20
Therefore the number of refills keith bought be 20 .
Make 31.75 y because that is the total cost he paid.
1.25x+6.75=31.75
1.25x=25
x=20
So he had 20 refills.

There's actually no such thing as "the formula for a triangle".
There are many details of a triangle that you might be asked
to calculate. You might be asked to find the perimeter, the area,
the angles, or the length of one or more sides. Your question
doesn't specify which of these things we're expected to find.
12-inch diameter costs $8.64, how much
should a pizza with a 16-inch diameter cost?
Answers
Answer: A 16 inch pizza is $11.52
Step-by-step explanation:
$8.64 / 12 = $0.72
$0.72 x 16 = $11.52
Take the amount ($8.64) and divide it by 12 (for the 12 inch pizza) and you get $0.72 for every inch of the pizza.
Then take $0.72 and times it by 16 (for the 16 inch pizza) and you get $11.52 and there is your answer.
Final answer:
Direct proportionality is used here to find the cost of a 16-inch pizza. Each inch of diameter costs $0.72, so a 16-inch pizza will cost $11.52.
Explanation:
The cost of a pizza in this instance is directly proportional to its diameter. Whenever such a situation arises, we use the concept of 'ratios' to determine the unknown value. In this particular question, the ratio of cost to diameter is the same for both pizzas.
The pizza with a 12-inch diameter costs $8.64, implying that every inch of diameter costs $8.64/12, or $0.72. If a 16-inch pizza is bought, the cost would then be 16 * 0.72, or $11.52.
