Respuesta :

From the question, It takes Ary an hour to write one thank you card.

So, the rate at which she writes the thank you card is;

[tex]\text{Rate R}=1\text{ card/hour}[/tex]

To determine the number N of thank you card she would write in 8 hours.

[tex]N=R\times T[/tex]

Where;

R is the rate = 1 card/hour

T is the time taken = 8 hours

Substituting the values we have;

[tex]\begin{gathered} N=1\text{ card/hour}\times8\text{ hours} \\ N=8\text{ cards} \end{gathered}[/tex]

The number of thank you cards she write is 8 cards
