Answer:

A.

Elena can run 3 miles per hour.

Step-by-step explanation:

Given that:

a circular running track = 1/5 mile

On this track, Elena runs completing each of the laps in 1/15 of an hour

We are to find Elena running speed.

It implies that the distance of Elena = \dfrac{1}{5}

Time to run each lap = \dfrac{1}{15} \ of \ an \ hour

Speed is the amount of distance covered in a specified period of time.

Recall that the formula for calculating speed is:

Speed = \dfrac{distance}{time}

Speed = \dfrac{\dfrac{1}{5}}{\dfrac{1}{15}}

Speed ={\dfrac{1}{5}\times \dfrac{15}{1}

Speed =  3miles / hour

As such, Elena can run 3 miles each hour.

Answer: you would have to purchase $1300 of merchandise and the total yearly amount paid to the warehouse for each plan is $1210

Step-by-step explanation:

Let x represent the number of dollars of merchandise that you would have to purchase in a year to pay the same amount under both plans.

Plan A offers an annual membership fee of $300 and you pay 70%, of the manufacturers reccomended list price. This means that the total cost of using plan A would be

300 + 0.7x

Plan B offers an annual membership fee of $40 and you pay 90% of the manufacturers reccomended list price.

This means that the total cost of using plan B would be

40 + 0.9x

For both plans to be the same,

300 + 0.7x = 40 + 0.9x

0.9x - 0.7x = 300 - 40

0.2x = 260

x = $1300

The total yearly amount paid to the warehouse for each plan would be

40 + 0.9 × 1300 = $1210

Adam is a salesperson in a video store. He is paid $100 every week plus a commission of $5 on every DVD he sells. Which equation
sweet [91]

Answer:

X = (150 - 100) / 5

Step-by-step explanation:

To determine how many DVDs Adam sold in the week, knowing that he charges a fixed amount of $ 100 plus $ 5 for each sale he makes, and in the week he charges a total of $ 150, the following calculation must be made:

X (number of DVDs sold) = (150 (weekly profit) - 100 (fixed amount)) / 5 (value of each DVD)

X = (150 - 100) / 5

X = 50/5

X = 10

So, during the week Adam sold 10 DVDs.
