Bogdan [553]

Answer:

the cost price is 27,715

Step-by-step explanation:

Let the cost price be x

As Amab sells to Vivek at 15% profit

So the selling price be

= 115 ÷ 100 × x = 1.15x

And Vivek sells to sagar at a profit of 10%

= 1.15x × 110 ÷ 100

= 1.265x

Now sagar pays it for 35,060

Sliva [168]

Answer:

89.132 inch

Step-by-step explanation:

“this shape is made up of one half-circle attached to a square with side lengths 16 inches. You can use 3.14 as an approximation.”

so, the square has a perimeter of 16 inch, four sides that will be 64 inch

then the half circle rule of perimeter of half circle: πr + 2r

=> perimeter of semicircle = π * 8 +2 * 8 = 41.132 inch

<em>without the bottom line of half circle= 41.132 -16 = 25.133 inch</em>

<em />

So total 25.133 + 64 =89.132 inch

If you invested $500 at 5% simple interest for 2 years, how much interest do you earn? Show work and answer in
givi [52]

Answer:

$50

$30.88

I will invest in simple interest as the interest there is more.

Step-by-step explanation:

If I invested $500 at 5% simple interest for 2 years, then the interest that I will get will be given by the formula

I = P \times \frac{rt}{100}, where P is the invested principal, r is the APR and t is the time in years.

So, in our case, I = 500 \times \frac{5 \times 2}{100} = 50 dollars. (Answer)

Now, if I invest $500 at 3% compound interest compounded monthly for 2 years.

Now, using the formula of compound interest we have

I = P(1 + \frac{r}{n \times 100} )^{tn} - P, where r is the APR and n is the number of times in a year the principal is compounded.

In our case, I = 500(1 + \frac{3}{12 \times 100} )^{2 \times 12} - 500 = 30.88 dollars. (Answer)

Therefore, I will invest in simple interest as the interest there is more. (Answer)
