• premium plan, with a membership fee of $240 and a cost of $11 per app\

question 5: what is the number of apps where the cost of no plan and a premium \\breakeven point\)?\
10\
question 6: if steve expects to download 15 apps, which plan should he choose?

Explanation:

Step1: Define variables for costs

Let $x$ = number of apps.
Cost of No Plan: $C_n = 35x$
Cost of Premium Plan: $C_p = 240 + 11x$

Step2: Solve for breakeven (Question5)

Set costs equal:
$$35x = 240 + 11x$$
Subtract $11x$ from both sides:
$$24x = 240$$
Divide by 24:
$$x = \frac{240}{24} = 10$$

Step3: Calculate costs for 15 apps (Question6)

No Plan cost:
$$C_n = 35 \times 15 = 525$$
Premium Plan cost:
$$C_p = 240 + (11 \times 15) = 240 + 165 = 405$$

Answer:

Question 5: 10
Question 6: Premium plan
