Chapter 1.5, Problem 3CYU

(a)

To determine

To calculate: To writean equation that can be used to find the number of ounces in any number of pounds

Answer to Problem 3CYU

The equation that can be used to find the number of ounces in any number of pounds is $y=16x$

Explanation of Solution

Given information: There are sixteen ounces in one pound

Calculation:

Given that there are sixteen ounces in one pound

Let the number of pounds be $x$

Thus, we get

  $1pound=16ounces$

  $xpounds=\left(16\times x\right)ounces$

  $=\left(16x\right)ounces$

Hence, the equation that can be used to find the number of ounces in any number of pounds is $y=16x$

(b)

To determine

To calculate: To make a function table to find the number of ounces in $5,8,11$ and 13 pounds

Answer to Problem 3CYU

Function table is

Number of Pounds	Number of ounces
5	80
8	128
11	176
13	208

Explanation of Solution

Given information: There are sixteen ounces in one pound

Calculation:

Given the equation that can be used to find the number of ounces in any number of pounds is $y=16x$

When $x=5$ , $y=16\left(5\right)=80$

When $x=8$ , $y=16\left(8\right)=128$

When $x=11$ , $y=16\left(11\right)=176$

When $x=13$ , $y=16\left(13\right)=208$

Thus, function table is given as

Number of Pounds	Number of ounces
5	80
8	128
11	176
13	208

(c)

To determine

To calculate: To graph the ordered pairs for the function

Answer to Problem 3CYU

Graph is sketched

Explanation of Solution

Given information: There are sixteen ounces in one pound

Calculation:

Given the function table as follows

Number of Pounds	Number of ounces
5	80
8	128
11	176
13	208

On plotting the above points on graph,
