Answer:
Probably ((6,9) + (4,6)) - (2,3)
Step-by-step explanation:
There is one 8 in each intervals: 1-10, 11-20, 21-30, 31-40, 41-50, 51-60, 61-70, 71-79, 90-100, and ten numbers with 8 in 80-89.
from 1-100, there are a total of nineteen 8's.
So from 101-200, there will be nineteen as well. Same goes for 201-300.
so,
19*3=57
There are fifty seven number with 8 from 1 to 300
Answer:
Invested at 11% : 3100
Invested at 6% : 3200
Step-by-step explanation:
let x= amount invested at 11%
let y= amount invested at 6%
we can write
Equation 1: x+y=6300
Equation2: .11x+.06y=533
Divide equation 2 by .06 to get
1.8333333x+y=8883.33333333
Subtract equation 2 from equation 1
.8333333x= 2583.33333333
x= 3100
Plug in x= 3100 into equation 1
3100+y= 6300
y= 3200
