Answer 2

Answer: $1.24, $2.22

Explanation:

Suppose one yoyo and 1 toy car costs x and y respectively.

According to question

5 yoyos and 2 toy cars costs $10.64

`\Rightarrow 5x+2y=10.64\quad \ldots(i)`

4 yoyos and 4 toy car costs $13.84

`\Rightarrow 4x+4y=13.84\quad \ldots(ii)`

Solve (i) and (ii)

`x=1.24,y=2.22`

Thus, 1 toy car costs $2.22
