Answer:

Loan A and B

Step-by-step explanation:

Since, the effective annual interest rate is,

i=(1+\frac{r}{n})^n-1

Where, r is the nominal rate( in decimals) per period,

n is the number of periods,

In Loan A :

r = 9.265% = 0.09265,

n = 52,

Thus, the effective annual interest rate is,

i_1=(1+\frac{0.09265}{52})^{52}-1

=(1+0.00178173077)^{52}-1

=1.09698725072-1

=0.09698725072\approx 0.9670

\implies i_1=9.670\%

In Loan B :

r = 9.442% = 0.09442,

n = 12,

Thus, the effective annual interest rate is,

i_2=(1+\frac{0.09442}{12})^{12}-1

=(1+0.00786833)^{12}-1

=1.09861519498-1

=0.09861519498\approx 0.9862

\implies i_2=9.862\%

In Loan C :

r =9.719% = 0.09719,

n = 4,

Thus, the effective annual interest rate is,

i_3=(1+\frac{0.09719}{4})^{4}-1

=(1+0.0242975)^{4}-1

=1.10078993749-1

=0.10078993749\approx 0.10079

\implies i_3=10.079\%

Since, i_1, i_2 but i_3>9.955\%

Hence, Loan A and B meets his criteria.

A brand of grape juice that's is 25% grape juice is mixed with another brand that is 75% grape juice. The result is 7 gallons of
garri49 [273]

Answer:

5.6 gallons.

Step-by-step explanation:

If we take x gallons of 25% grape juice then it will contain \frac{x}{4} gallons of pure grape juice.

Again, if we take y gallons of 75% grape juice then it will contain \frac{3y}{4} gallons of pure grape juice.

If we mix them then the total volume will become x + y = 7 gallons  ...... (1)

Again the mixture will become 35% juice.

So, \frac{\frac{x}{4} +\frac{3y}{4} }{x+y} =\frac{35}{100}

⇒ 0.25x + 0.75y = 0.35x + 0.35y

⇒0.1x = 0.4y

⇒x = 4y........ (2)

Now, solving equations (1) and (2) we get, 5y = 7, ⇒ y = 1.4 gallons

Hence, x = 4y = 5.6 gallons

Therefore, the 25% grape juice was mixed by 5.6 gallons. (Answer)
