A student scores 73 out of 100 on a test. If the maximum score on the next test is also 100​ points, what score does the student
vesna_86 [32]
Because the student scored 73/100 on the first test, their current average is 73%.

To calculate the avergae with the next test score, you add both percentages the student gets together and then divide by 2.

79 = (73 + x) / 2

Multiply by 2 on both sides

158 = 73 + x

Subtract 73 on both sides

x = 85

So the student needs to get at least an 85/100 on the next test to maintain a 79 average.

Dahlia is trying to decide which bank she should use for a loan she wants to take out. In either case, the principal of the loan
Verdich [7]

Answer:

a.  Loan Q’s finance charge will be $83.73 greater than Loan P’s.

Step-by-step explanation:

To solve this, we will use the formula for loan payment:

P=\frac{\frac{r}{n}(PV) }{1-(1+\frac{r}{n} )^{-nt} }

Here,

P is the payment  ; PV is the present debt; r is the interest rate; n is the number of payments per year; t is the time

Working for bank P:

PV = 19450

r = 5.8 or 0.058

t = 9

n = 12

Putting the values in the formula we get:

P=\frac{\frac{0.058}{12}(19450) }{1-(1+\frac{0.058}{12} )^{-12*9} }

Solving this we get:

P= $231.59

Dahlia's monthly payment is $231.59. So,her total payment for 9 years will be = 231.59\times9\times12=25011.72

Finance charge will be = total future value minus loan amount plus service charge.

= (25011.72-19450)+925 = $6486.72

Hence, the total finance charge of bank P is $6,486.72

Working for bank Q:

PV = 19450

r = 5.5 or 0.055

t = 10

n = 12

Putting the values in the formula we get:

P=\frac{\frac{0.055}{12}(19450) }{1-(1+\frac{0.055}{12} )^{-12*10} }

Solving this we get:

P= $211.08

Dahlia's monthly payment is $231.59. So,her total payment for 10 years will be = 211.08\times10\times12=25329.60

Finance charge will be = (25329.60-19450)+690.85=6570.45

Hence, the total finance charge of bank Q is $6570.45

Now we will find the difference between both bank's finance charges:

6570.45-6486.72=83.73 dollars

So, we can say that Loan Q’s finance charge will be $83.73 greater than Loan P’s.
