Alright! We know that the total number of students is 100%. So, if 65% of the students brought a hot lunch, in order to find how many students brought a packed lunch you subtract it from 100%:

[100 - 65] = 35

So 35% of the students brought a packed lunch. Now, in order to find the fraction of students you simply put 35% of students over the total percent of students (100%)"

[35/100]

Then you simply:

[35/100] ⇒ [7/20]

The answer is 7/20ths of the students brought a packed lunch.

lord [1]

Answer:

Paul's salary is increased by 6% and John's salary is 2 more than thrice Paul's salary.

Step-by-step explanation:

Paul and John are working in a Company and this month Paul's salary is increased by 6%. John's salary is 2 more than thrice Paul's salary.

If <em>x </em>represents Paul's salary before increment, and <em>y</em> represents John's current salary, find Paul's current salary.

<em>x </em>is Paul's salary before increment.

So, Paul's current salary = <em>x</em> + 6% of <em>x</em>

= <em>x</em> + 0.06<em>x</em>

= 1.06<em>x</em>

John's current salary is 2 more than thrice Paul's salary.

So, John's current salary = 3(1.06<em>x</em>) + 2.

Mark reads 42 pages of a book every 3/4 hour. Write an equation that models the relationships between x, the number of hours Mar
Illusion [34]

Answer:

The equation that models the relationships between x, the number of hours Mark reads, and , y the number of pages of the book he reads is:

y=56x

Step-by-step explanation:

Given:

Mark reads 42 pages every \frac{3}{4} hour.

The number of hours is given by = x

The number of pages is given by =y

The equation can be modeled as:

y=mx+b

where m represents rate of change and b represents the y-intercept or the initial value.

Rate of change ==\frac{Change\ in\ y}{Change\ in\ x}=\frac{42}{\frac{3}{4}}=42\times \frac{4}{3}=56

The initial value b=0 as Mark starts reading from 0.

So, the equation is:

y=56x
