To determine if the family will have enough money for their vacation by the end of August, we first need to calculate their monthly deposits.
- Initial amount: $125
- Desired vacation cost: $1362
- Monthly increase of deposits: 20% more than the previous month
Monthly Deposits Calculation
- Month 1 (March): Deposit = $125
- Month 2 (April): Deposit = $125 + (20% of $125) = $125 + $25 = $150
- Month 3 (May): Deposit = $150 + (20% of $150) = $150 + $30 = $180
- Month 4 (June): Deposit = $180 + (20% of $180) = $180 + $36 = $216
- Month 5 (July): Deposit = $216 + (20% of $216) = $216 + $43.20 = $259.20 (rounded to $259)
- Month 6 (August): Deposit = $259 + (20% of $259) = $259 + $51.80 = $310.80 (rounded to $311)
Total Savings Calculation
Now, let's sum up the total savings by the end of August:
- March: $125
- April: $150
- May: $180
- June: $216
- July: $259
- August: $311
Total Amount Saved:
\[ Total\ Savings = 125 + 150 + 180 + 216 + 259 + 311 = 1241 \]
Determine if They Have Enough:
Now, we compare the total savings with the vacation cost:
- Total Saved: $1241
- Vacation Cost: $1362
Difference:
\[ Difference = Vacation Cost - Total Saved = 1362 - 1241 = 121 \]
Therefore, the family does not have enough money for their trip.
Conclusion:
A. No, they need $121 more.
