Answer:

D

Step-by-step explanation:

you need to first do 5.89- [(5.89 * 15)/100]=5.89-0.8835=5.0065

then 5.0065 * 2 = 10.013 because it is 15% each dozen then

[(10.013 * 5)/100] =0.50065 then 10.013 - 0.50065 = 9.51235

and lastly (9.51235 * 7)/100 = 0.6658645

finally 9.51235 + 0.6658645= 10.1782145

and then you just need to round it to the nearest hundredths and you will get 10.18
