B. 7

Step-by-step explanation

Step 1

Let the rosita's mom age=45

a represents the age of rosita

and

the rosita's mom age=42

she is six times as old as Rosita,so


6a=42

Step 2

solve the equation


\begin{gathered} 6a=42 \\ \text{divide both sides by 6} \\ (6a)/(6)=(42)/(6) \\ a=7 \end{gathered}

it means the age of rosita is 7

so, the answer is

B.7

I hope this helps you
