A newly opened juice shop earned a profit of $2,400 in the first month. For the remaining months of the year, the expected profi

atroni [7]

First month's profit of the company = $2,400.

After the first month, the profit is modeled by the function

J(t) = 2.5t + 1,250, t is the number of months after the first month the shop opened.

Now, P(t) describes the total profit earned by the company.

So, P(t) = (Profit earned from first month) + (Profit earned from remaining 11 months of the year)

= 2400 + (2.5t + 1250)

<u><em>= 2.5t + 3650</em></u>

Hence, total profit earned for the year = 2.5t + 3650.

A paintball court charges an initial entrance fee plus a fixed price per ball.

m_a_m_a [10]

Answer : The cost of 10 balls will be, 13.5 dollars

Step-by-step explanation :

As we are given the following expression:

$P=0.80\times n+5.50$

where,

P = total price (in dollars)

n = number of balls used

Given:

n = number of balls used = 10

Now we have to determine the cost of 10 balls.

$P=0.80\times n+5.50$

$P=0.80\times (10)+5.50$

$P=8+5.50$

$P=13.5\$$

Thus, the cost of 10 balls will be, 13.5 dollars
