According to the accountant's estimates, if the same business trips will be made next year as this year, how much money should be allotted for train fares and airfares next year?

A. $18,700

D. $21,130

Can some experts show me the best solution in this?

Calculate 107500+11200=18700
With 10% increase the amount would be 18700x1.1=20570
Additional 5% increase in 11200 is 560
Hence total money he should allot for next year=20570+560=21130
Option D is correct.

Hi lheiannie07,
Let's take a look at your question.

Train fares for business trips this year = $7,500
10% increase in train fares business trips next year = 7,500 * 10% = 7500 * 0.1 = $750
Total Train fares for business trips next year = $7,500 + $750 = $8,250

Air fares for business trips this year = $11,200
15% increase in air fares for business trips next year = 11,200 * 15% = 11,200 * 0.15 = $1,680
Total Air fares for business trips next year = $11,200 + $1,680 = $12,880

Total money allotted for next year business trips = $8,250 + $12,880 = $21,130

Therefore, Option D is correct.

Hope it helps.
