The price of one share of Acme Company declined $3.50 per day for 4 days in a row. What is the overall change in price of one share?

Answers

Answer:

The overall change in price of one share is: -$14.00

Step-by-step explanation:

The Acme Company share has declined its price in a rate of $3.50 per day

Therefore the change rate is: $- (\mathdollar 3.50)/(day)$

In order to find the overall change in prince in 4 days in a row, we must have to multiply the change rate by 4 days

$( - (\mathdollar 3.50)/(day))(4 \ days)= - \mathdollar 14.00$

Therefore, the overall change in price is: -$14.00

Since it's a decline, the amount will be negative.
3.5 per day for 4 days so multiply 3.5 by 4, which equals: $14
so the overall change is -$14.00

What is surface area?

The surface area of any shape is the area of the shape that is faced or the Surface area is the amount of area covering the exterior of a 3D shape.

Here,
Area of the sprinkler,
= area of the circle
= πr²
= 3.14 × 4²
= 50.24
≈50

Thus, the required area that the sprinkler will cover is 50 square feet. Option C is correct.
