Answer:
1/4 upperclassmen are not involved in enrichment.
Step-by-step explanation:
"3/4 of the upperclassmen (sophomores thru seniors) are involved in an enrichment." That leaves 1/4 upperclassmen students left. Verification: 3/4 + 1/4 = 4/4. 4/4 is also 1 whole.
Basically, you have to do 755/12.5 That will give you your average per minute.
Its the last one because 10 times 1 is 10 and 0 plus 10 still gives you 10
You add them and then it would be 30.6898033492
Can you take a picture of the problem?
