Question

Carys calculates the total amount E, in dollars, that she earns for working h hh hours using the equation E=10h. How many dollars does Carys earn per hour? At that rate, how many hours does it take Carys to earn one dollar?

Answer 1

if an hour is able to be split up for payment then it will be 1/10 of an hour

Answer 2

Answer: Carys earns $10 per hour and  earn $1 in $\frac{1}{10}$ hour .

Step-by-step explanation:

Given: Carys calculates the total amount E, in dollars, that she earns for working h hours.

She use the equation to calculate the total amount  $E=10h$.

Foe h=1, $E=10(1)$

$\Rightarrow\ E=\ 10$

hence, she earns $10 in one hour.

Therefore, Carys earns $10 per hour.

Let she earn $1 then put E=1 in the equation, we get

$1=10h\\\Rightarrow\ h=\frac{1}{10}\ hour$

Hence, she earn $1 in $\frac{1}{10}$ hour .
