Troista Mobile Accessories sells mobile apps on their Web site. If a customer spends on average, $12 per visit and visits the We
Leno4ka [110]

Answer: The required average is $576.

Step-by-step explanation:

Since we have given that

Percent of customers not returning each year = 25%

Average customer lifetime = \dfrac{1}{0.25}=4\ years

Percent of margin on the average bill = 60%

Cost per visit = $12

Number of times each year visited = 20 times

So, Average expense by each customer per year = 12\times 20=\$240

Average margin = 60% of 240 = 0.6\times 240=\$144

Average non discounted gross profit during a customer's lifetime is given by

144\times 4=\$576

Hence, the required average is $576.

Sup yall<br><br> solve 4p-7r=pq+16 for p
kykrilka [37]

Answer:

p = (7r+16) / (4-q)

Step-by-step explanation:

4p - 7r = pq + 16

Add 7r to both sides.

4p = pq + 16 + 7r

Subtract pq from both sides.

4p - pq = 7r + 16

Factor out p from the left side.

p(4 - q) = 7r + 16

Divide both sides by (4 - q).

p = (7r + 16)/(4 - q)

The 7r and the 16 could be in either order, like 7r+16 or 16+7r. You could show that the answer is a fraction with 7r+16 on top and 4-q on the bottom. If you are writing or on the computer selecting a fraction that is stacked you don't need need the parenthesis.
