Answer: 25 nickels
Step-by-step explanation:
EQUATIONS:
quantity: n + d = 63
value: 5n + 10d = 505
-------------------------
Divide thru the 2nd equation by 5 to get:
n + 2d = 101
----------------
Subtract that from the 1st equation:
-d = -38
d = 38 (# of dimes)
---------------
Substitute that into n+d=63 to solve for "n":
n + 38 = 63
n = 25 (# of nickels)
Answer:
4.3
Step-by-step explanation:
mean=sum of the terms/number of term
room A=3+20+25+0+0+0=25
Room B= 2+18+4+0+0+0=24
room C= 28
room D= 21
room E= 32
step(2)
25+24+28+21+31=130/30
= 4.3
