Question

2. Rico wants to buy battery-operated toy car which costs ₱587.50 He already saved ₱150.00. His ninong gave him ₱200.00. If he saves ₱12.50 a day from his allowance, how long will it take him to save the rest of the money to buy the toy car

Answer 1

Rico already has 350.00 from his savings and the amount his ninong gave him; this means that he only needs to save:

`587.50-350.00=237.50`

more.

Let x be the number of days he is going to save, since he saves 12.50 each day then for x days he will have 12.5x, we need this to be equal to 237.50 then we have the equation:

`\begin{gathered} 12.5x=237.50 \\ x=(237.50)/(12.50) \\ x=19 \end{gathered}`

Therefore he needs to save for 19 days.
