Leona [35]

Answer:

$\frac{7}{12}$ miles.

Step-by-step explanation:

Please consider the complete question.

Bay View Bike Path is 7/8 miles. Keisha is riding her bike on Bay View bike path. Keisha's bike got a flat tire 2/3 of the way down the oath and she had to stop. How far did Keisha ride?

To find the distance covered by Keisha while riding the bike, we need to find 2/3 of 7/8 miles.

$\text{Distance that Keisha ride}=\frac{2}{3}\times \frac{7}{8}$

$\text{Distance that Keisha ride}=\frac{1}{3}\times \frac{7}{4}$

$\text{Distance that Keisha ride}=\frac{1\times 7}{3\times 4}$

$\text{Distance that Keisha ride}=\frac{7}{12}$

Therefore, Keisha ride $\frac{7}{12}$ miles.

Elan Coil [88]

Answer:the function representing profit, P = 3n + 200

Step-by-step explanation:

The function C = 2n + 200 represents his costs, in dollars, for producing n jars of salsa.

The revenue, or the amount he receives for selling n jars, can be represented by the function R = 5n.

Profit = revenue - cost or expenses.

Therefore,

The function representing Dominic's profit, P, for selling n jars of salsa will be

P = 5n - 2n + 200 = 3n + 200
