Joe's Plumbing and Mark's Plumbing have different ways of charging their customers. The function defined by J(t)=45t represents

puteri [66]

Answer:

Joe's Plumbing charges more per hour ($45) than Mark's Plumbing (S40)

Step-by-step explanation:

Let

t ------> the number of hours

J(t) ---->the total amount in dollars that Joe's Plumbing charges

M(t) ---->the total amount in dollars that Mark's Plumbing charges

we know that

The linear equation in slope form is equal to

$f(x)=mx+b$

where

m is the slope or rate of the linear equation

b is the y-intercept (initial value)

In this problem we have

<em>Joe's Plumbing</em>

$J(t)=45t$

The slope or rate is equal to

$m=\$45\ per\ hour$

$b=\$0$

Mark<em>'s Plumbing</em>

$M(t)=40t+25$

The slope or rate is equal to

$m=\$40\ per\ hour$

$b=\$25$

therefore

Joe's Plumbing charges more per hour ($45) than Mark's Plumbing (S40)

A cosmetics company tested a new lotion. Of the 2,500 people tested, 15 had an allergic reaction. What percent of the people tes

DIA [1.3K]

If we want to know what percent of a number A is of another number B, then all we have to do is to simply divide number A by number B. Then either we move the decimal place of the answer two places to the right or multiply the answer with 100, either method results in the same number.

So the percent of tested people who had an allergic reaction to the new lotion is:

percent people = (15 / 200) * 100

percent people = 0.075 * 100

percent people = 7.5%

Therefore 7.5% of the people had allergic reaction.
