Final answer:
Miguel spent about $23.07 in the toy store.
Step-by-step explanation:
Miguel spent $9.75 on balloons, $5.20 on rubber spiders, and $7.12 on a model race car. To find out how much money Miguel spent in total, we need to add up these amounts.
First, we add $9.75 and $5.20: $9.75 + $5.20 = $15.95. Then, we add $15.95 and $7.12: $15.95 + $7.12 = $23.07. Therefore, Miguel spent about $23.07 in the toy store.
