Question 10 (7 points) d Elizabeth borrowed $20,000 for five years at a 5% annual interest rate, what is her monthly payment, to
zhenek [66]

Answer:

monthly payment is $377

C is the correct option.

Step-by-step explanation:

The formula for the monthly payment is given by

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

Given that,

P =  $20,000

n = 5 years = 60 months

r = 0.05

Substituting these values in the formula

C=\frac{20000\cdot \frac{0.05}{12}(1+\frac{0.05}{12})^{60}}{(1+\frac{0.05}{12})^{60}-1}

On simplifying, we get

C=\$377.425\\\\C\approx \$377

Therefore, the monthly payment is $377

C is the correct option.

Aladdin found a cave filled with boxes of gold, measuring 2 inches × 2 inches × 2 inches, and boxes of silver, measuring 1 inch
PIT_PIT [208]

Answer:

Aladdin took 32 boxes of treasure.

Step-by-step explanation:

The dimensions of the box Aladdin brought are 6 inch × 6 inch × 7 inch.

Since, the volume of the box = Length × Width × Height.

So, the volume of the Aladdin's box = 6 × 6 × 7 = 252 inch³

Now, the dimensions of the gold box are 2 inch × 2 inch × 2 inch.

So, the volume of the gold box = 2 × 2 × 2 = 8 inch³

Thus, the number of gold boxes which can fit inside Aladdin's box = \frac{252}{8} = 31 boxes

Also, as the dimensions of the silver box are 1 inch × 1 inch × 1 inch.

So, the volume of the silver box = 1 × 1 × 1 = 1 inch³

Then, the number of silver boxes which can fit inside Aladdin's box is 1.

Hence, Aladdin took 31 + 1 = 32 boxes of treasure.
