Answer:
Step-by-step explanation:
To advise Mona on how to save for her new phone, let's break down her savings into fractions, decimals, and percentages to understand her progress better.
First, Mona saves 10% of her daily allowance. To convert 10% into a decimal, divide 10 by 100, which gives 0.10. Therefore, if Mona’s daily allowance is P200, then she saves \( 200 \times 0.10 = P20 \) per day.
In addition to her daily savings, Mona receives P5,000 in Christmas gifts. To compute her total annual savings from both sources, we need to calculate her daily savings over the year. Assuming there are 365 days in a year, her total daily savings amount to \( 20 \times 365 = P7,300 \). Adding her Christmas gift of P5,000, her total savings for the year is \( 7,300 + 5,000 = P12,300 \).
Given that her mom will double this amount, Mona would end up with \( 2 \times 12,300 = P24,600 \) by the end of the year.
Since Mona's phone costs P25,000 and her projected savings are P24,600, she will be short by \( 25,000 - 24,600 = P400 \). To cover this shortfall, Mona might consider either saving a little extra from her allowance or finding additional sources of income or gifts. Alternatively, she could aim to save an additional P400 to reach her target amount before buying the phone.
In summary, Mona is on track with her savings strategy, but she should plan to save a bit more or explore additional ways to bridge the small gap to afford the phone.
