Answer:
she worked 9 hours at sporting goods store and 6 hours on piano lessons.
Step-by-step explanation:
total hours=15
8.47x + 17(15-x) = 178.23
8.47x + 225 - 17x = 178.23
225 - 178.23 = 17x - 8.47x
76.77 = 8.53x
x = 76.77 / 8.53
x = 9
therefore she worked 9 hours at sporting goods centre and the remaining hours (15-9) giving piano lessons.
