Answer:
Sam: $30; Bethan: $24
Step-by-step explanation:
Since the ratio is 5:4 Sam has to pay 5/9 of the total which is 54. To find how much he pays set up the equation like this.
Cross Multiply
54(5)=9x
270=9x
Divide by 9
30=x
So Sam pays $30. To find out how much Bethan pays simply subtract 30 from 54
54-30=24
So Bethan pays $24
Given:
average daily balance: $20
daily periodic rate: 0.04%
number of days in the cycle = 30 days
0.04% ÷ 100% = 0.0004
0.0004 x 20 = 0.008 daily finance charge
0.008 x 30 = 0.24 monthly finance charge
0.24 or <span>B. 24¢</span>
Answer:
first step is to put the (x-9)^2 into a standard form which is y=x^2−18x+81 then choose two integers larger than the x-value of the vertex point.next choose two integers smaller than the x-value of the vertex point. lastly substitute these values in place of "x" in the equation and solve for "y".
Step-by-step explanation:
x | y
7 | 4
8 | 1
9 | 0
10 | 1
11 | 4
4=(11-9)^2
1=(10-9)^2
0=(9-9)^2
1=(8-9)^2
4=(7-9)^2
