Rey Pennington · Answer 1

26 hours

Step-by-step explanation:

One group will donate $15 per hour, while the other is offering a flat sum of $110. She wants $500, so we can set up the equation

15x + 110 = 500 (with x being the number of hours Traci dances). You subtract 110 from 500 to isolate the variable with its coefficient, resulting in

15x = 390. Then, dividing 390 by 15 to get x by itself, the answer of 26 hours is found.
