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. Write an equation you can use to find the number of refills that Keith bought.
1.25r + 6.75 = 31.75
Solve the equation: -29.5u+548=2,023
Solve the equation: -29.5u+548=2,023
To find the number of refills that Keith bought, we can set up an equation using the given information.
Let's assume that Keith bought "x" refills.
We know that the cost of the mug itself is $6.75, and each refill costs $1.25. So the total cost Keith spent on refills is (x * $1.25).
The equation to find the number of refills Keith bought can be expressed as:
6.75 + (x * 1.25) = 31.75
In this equation, we add the cost of the mug to the cost of "x" refills and set it equal to the total amount Keith spent ($31.75).
Solving this equation will give us the value of "x," which represents the number of refills Keith bought.
