Answer:
Finance charge = $2.39
Step-by-step explanation:
A finance charge is the cost of borrowing money, including interest and other fees. It can be a percentage of the amount borrowed or a flat fee charged by the company.
In the given question we will calculate the amount of the finance charge
Finance charge= Previous balance×(Annual rate÷12months)
Finance charge=179.32×(16/100÷12months)
Finance charge=179.32×(0.16÷12months)
Finance charge=179.32× 0.0133
=$2.39
New balance= previous balance-payments/credit+finance charge+New purchases
New balance=179.32−85+2.39+117.42
=$214.13
Answer:
Time taken by Anna = x = 5.6 hours
Explanation:
Strategize. Let x = Anna's time.
We know that, d = s*t
Where,
d is distance
s is speed
t is time
Distance covered by Allen = 7 times 40 = 7*40 = 280
Distance travelled by Anna = x times 50 = 50x
Set up. 7(40)=x(50)
280 = 50x
Solve for x
x = 
x = 5.6 hours
Identify. Anna's time is the unknown.
Solve. x = 5.6
Check. 7(40)=5.6(50)
280 = 280
You're right!
That's the final answer.
I hope it will help you.
Answer:
Sam sokey 0.5 hours biking and 3.5 hours walking
Step-by-step explanation:
Here, we want to know the number of hours spent walking and biking
Mathematically; distance = speed * time
Let the number of hours spent walking be x and the number of hours spent biking be y
Mathematically;
x + y = 3 •••(i)
distance spent walking = 4 * x = 4x miles
distance spent biking = 12 * y = 12y miles
4x + 12y = 20
divide through by 2
2x + 6y = 10 ••••••(ii)
From i , x = 4-y
Substitute this into ii
2(4-y) + 6y = 10
8 - 2y + 6y = 10
8 + 4y = 10
4y = 10-8
4y = 2
y = 2/4 = 0.5 hours
The number of hours spent walking = 4-0.5 = 3.5 hours
