Question

Avery noticed that 9 so of the apples in a basket are red. There are 45 red apples in the basket. (a) Represent the situation with an equation. Use a for the variable. (b) Solve the equation in Part (a). Show your work. (c) What does the solution of the equation represent in the situation?

Answer 1

a)

Let a be the number of red apples in the basket. We know that 9/10 of the apples are red and that we have a total of 45 apples, then we have the equation:

$a=\frac{9}{10}(45)$

b)

Let's solve the equation:

$\begin{gathered} a=\frac{9}{10}(45) \\ a=40.5 \end{gathered}$

Hence we have that a=40.5

c)

The solution tells us that apporximately 40 or 41 apples are red.
