There were 32 toys on the toy store shelf. We know that there were 19 cars with these toys. We also know that 18 of these toys were made of wood. How many wooden cars were on the shelf? Find at least two solutions.

Correct answer:

a =  5
b =  18

Step-by-step explanation:

$$\begin{gathered} s=32 \\ A=19 \\ D=18 \\ a\le x\le b \\ a=A+D-s=19+18-32=5 \end{gathered}$$

$b=\min (A,D)=\min (19,18)=18$
