B in the answer <span>not correctly written in scientific notation</span>
Answer:
5545
Step-by-step explanation:
X% of 4 = x*4/100 = 0.04x
y% of 5 = x*5/100 = 0.05y
x% of 4 + y% of 5 = 0.04x + 0.05y
How you express a number, n, as percentage of 11?: [n/11]*100= 9.10n %
Then make n = 0.04x + 0.05y
9.10n %= 9.10[0.04x + 0.05y] %= (0.3656x + 0.455y)%
.
