o-na [289]

Answer:

m = 18

Step-by-step explanation:

Given :

=> -15 is a root of the polynomial

=>  It is a zero to the solution.

Process :

Substitute -15 in place of x.

=> (-15)² + (-15)m + 45 = 0

=> 225 + 45 - 15m = 0

Alberto’s monthly income is $3,200. Part of Alberto’s monthly budget is shown in the table.
Sladkaya [172]

Using the percentage concept, it is found that 40% of Alberto’s income is used to pay for his rent and groceries.

<h3>What is a percentage?</h3>

The percentage of an amount a over a total amount b is given by a multiplied by 100% and divided by b, that is:

P = \frac{a}{b} \times 100\%

In this problem:

  • Alberto’s monthly income is $3,200, hence b = 3200.
  • He spends 896 + 384 = $1280 in rent and groceries, hence a = 1280.

Then, the percentage is given by:

P = \frac{1280}{3200} \times 100\% = 40\%
