Shazia sells 25x^2+5x+5 flowers in one day. If she sells the same number of flowers each day for rs 5x each , how much money wil

Mumz [18]

Answer:

$Total = 625x^3 + 125x^2 + 125x$

Step-by-step explanation:

Given

$Flowers = 25x^2 + 5x + 5$

$Unit\ price = 5x$

Required

The total price for 5 days

First, calculate the total for a day.

$1\ day = Unit\ price * Flowers$

$1\ day = 5x * (25x^2 + 5x + 5)$

Open bracket

$1\ day = 125x^3 + 25x^2 + 25x$

For 5 days, the total will be.

Total = days * sales of a day

So, we have:

$Total = 5 * [ 125x^3 + 25x^2 + 25x]$

$Total = 625x^3 + 125x^2 + 125x$

If two events are independent, then P(A and B) = P(A) x P(B).

In your situation, you need to solve 0.185 = 0.25 x P(B).

Can you take it from there?
