Oliver is buying a deck of cards for each of his eight nieces and nephews. Let d equal the price of onedeck of cards. If he wants to spend less than thirty dollars, how much could each deck of cards cost?

Respuesta :

Given that Oliver want to buy a deck of cards for each of his eight neices and nephews;

and each deck of cards cost d.

the total costis;

[tex]8\times d=8d[/tex]

If he wants to spend less than thirty dollars, it means;

[tex]8d<30[/tex]

to get the value of d, let's divide both sides by 8;

[tex]\begin{gathered} \frac{8d}{8}<\frac{30}{8} \\ d<3.75\text{ dollars} \end{gathered}[/tex]

The cost of each deck could be any amount less than $3.75

[tex]d<\text{ \$}3.75[/tex]
