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)

= 2.5t + 3650

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

larisa [96]

Answer:

A 190-pound person would burn 285 calories at the same rate.

Step-by-step explanation:

Calories burn depends on the weight

Weight of first person = 160

Calories burn for 160 pounds in 30 mins = 237

Calories burn rate for 1 pound in 30 mins = $\frac{237}{160}$ = 1.5

Calories burn for 190 Pound person would be:

Weight of second person = 190

Calories burn for 190 pounds in 30 min:

As the burn rate of calories is same for the two persons:

= rate × weight

= 1.5 * 190

= 285 calories
