Norma prepared 10.65 kilograms of dough after working 6 hours. How many hours did Norma work if she prepared 14.2 kilograms of dough? Assume the relationship is directly proportional.

Respuesta :

ANSWER:

8 hours

STEP-BY-STEP EXPLANATION:

Since the relationship is directly proportional, we can make the following proportion, taking into account the data given in the statement:

[tex]\frac{6}{10.65}=\frac{x}{14.2}[/tex]

We solve for x:

[tex]\begin{gathered} x=\frac{6\cdot14.2}{10.65} \\ x=8\text{ hours} \end{gathered}[/tex]

Therefore, the number of hours would be 8 hours
