Answer: 45 total, 11 minutes on science
Step-by-step explanation:
in the first sentence, it says that joey spends 45 minutes total every day. the problem wants how long joey spent on his science homework every day. since it says he spends 14 minutes on math and 20 on reading, we can add those to get 34 minutes. to find the remaining minutes, subtract 45 (the total time) from 34 (time from math and reading) and you would get 11 minutes, which would be his science homework time :)
