Answer: We can use the following equation to find Xavier's current hourly pay rate:
x * 20 * 1.15 = 253
where x is his current hourly pay rate, 20 is the number of hours he works each week, and 1.15 represents the 15% pay raise.
To solve for x, we can simplify the equation as follows:
x * 23 = 253
x = 253/23
x ≈ 11
Therefore, Xavier's current pay rate is approximately $11 per hour.
