Final Answer:
Felicia needed to retile x square feet in her bathroom. She used a total of y cases of tile to complete the job. Each case of tile she used reduced the area remaining to be retiled by z square feet.
Step-by-step explanation:
Felicia needed to retile a total of x square feet in her bathroom. She used y cases of tile, and each case reduced the area remaining to be retiled by z square feet. To find the total area she retiled, we can use the formula: Total area = Initial area - (Number of cases used Reduction per case). Substituting the given values, we get: Total area = x - (y z).
For example, if Felicia needed to retile 100 square feet, used 5 cases of tile, and each case reduced the area remaining by 10 square feet, the calculation would be: Total area = 100 - (5 * 10) = 100 - 50 = 50 square feet.
In summary, Felicia’s total retiled area can be calculated using the formula Total area = Initial area - (Number of cases used * Reduction per case), where x represents the initial area, y represents the number of cases used, and z represents the reduction per case.
