Answer:
We only need to calculate the 15% of 44.99 and 49.99 and sum them, for that, we have to multiply each number by 0.15:
44.99 * 0.15 + 49.99 * 0.15 = 14.27
He saved 14.25 (you should put the unit it's).
We could also have done a rule of three (which is what we have really did before)
44.99 - 100%
x - 15%
x = =. 6.75
49.99 - 100%
x - 15%
x = = 7.5
6.75 + 7.5 = 14.25
