Let C ( t ) be the number of US cell phone subscribers in millions in t years since 1995. A linear model for the data is F ( t )

Andru [333]

ANSWER

In 16 years time.

EXPLANATION.

If the number of subscribers is 324 million, then it means

$f(t)=324$

But we were given that,

$f(t)=18.997t+16.711$

This implies that,

$324=18.997t+16.711$

We now solve for t,

$324-16.711=18.997t$

$307.289=18.997t$

$\frac{307.289}{18.997}=t$

$16.17566=t$

That will be approximately in the 16th year.

A landscaper needs 348 pounds of plant food. He has 114 pounds in his truck, and another 46 pound at his shop.

Black_prince [1.1K]

Answer:

$\frac{19}{12}\ pounds$

$1\frac{7}{12}\ pounds$

Step-by-step explanation:

<u><em>The correct question is </em></u>

A landscaper needs 3 4/8 pounds of plant food. He has 1 1/4 pounds in his truck, and another 4/6 pound at his shop. How many more pounds of plant food does the landscaper need?

Let

x ----> the additional pounds of plant food needed for the landscaper

we know that

The additional pounds of plant food needed for the landscaper plus the pounds in his truck plus the pounds in his shop must be equal to the total pounds of plant food needed

The linear equation that represent this problem is

$x+1\frac{1}{4}+\frac{4}{6}=3\frac{4}{8}$
