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 = $\frac{15*44.99}{100}$ =. 6.75

49.99 - 100%

x - 15%

x = $\frac{15*49.99}{100}$ = 7.5

6.75 + 7.5 = 14.25
