first decompose 15 which is 10 + 5

then make them percents like 10% and 5 %

supposing the price were 942,

10 % would be 94.2, 5% would be half 47.1

add 94.2 and 47.1 = 94.2 + 47.1 = 141.3

141.3 would be the 15%

then add 141.3 to 942 = 141.3 + 942 = 1083.3

so if I added 15 % 942 to 942 I would get 1083.3
