jarptica [38.1K]

Answer:

Total amount pay for dinner = Rs 1,014

Step-by-step explanation:

Given:

Amount pay for food = Rs 900

Percentage of sales tax = 1%

Percentage of trip payment = 15%

Find:

Total amount pay for dinner

Computation:

Amount pay for sales tax = Amount pay for food x Percentage of sales tax

Amount pay for sales tax = 900 x 1%

Amount pay for sales tax = 900 x 0.01

Amount pay for sales tax = Rs 9

Amount pay for trip = Amount pay for food x Percentage of trip payment

Amount pay for trip = 900 x 15%

Amount pay for trip = 900 x 0.15

Amount pay for trip = Rs 105

Total amount pay for dinner = Amount pay for food + Amount pay for sales tax + Amount pay for trip  

Total amount pay for dinner = 900 + 105 + 9

Total amount pay for dinner = Rs 1,014
