Given:
Karen earns $54.60 for working 6 hours.
Amount she earns varies directly with the number of hours she works.
She need to work to earn an additional $260.
To find:
Number of hours she need to work to earn an additional $260.
Solution:
Let the amount of earnings be A and number of hours be t.
According to question,

...(i)
where, k is constant of proportionality.
Karen earns $54.60 for working 6 hours.

Divide both sides by 6.


Put k=9.1 in (i).

Substitute A=260 in the above equation.

Divide both sides by 9.1.



Therefore, she need to work extra about 29 hours to earn an additional $260.

Step-by-step explanation:
I was only able to finish one through eight The rest follow the same concept though
<span>Presumably, the opposite of decimals are fractions because by dividing the two numbers you get the decimal value of the fractional form of the number. Refer to the example below.
How do you write 39/100 into a decimal form is by simply dividing 39 to 100. </span>
<span>Hence, </span>
1. 39 / 100 = 0.39 -> Hence this is the decimal form.
<span>0.39 is the decimal form of the given value. </span>
<span>Other examples can include: </span>
<span><span>1. </span> 100 / 1000 = 0.1</span> <span><span>
2. </span> 45 / 10 = 4.5</span><span>
