Example 15 Lhamo and Norbu went to a hotel. Each of them ordered a vegetable cutlet and a rasgulla. A vegetable cutlet costs ₹43 and a rasgulla costs ₹24. Write an expression for the amount they will have to pay. Cost of vegetable cutlet = Rs 43 Cost of rasgulla = Rs 24 Now, Total amount they have to pay = 2 people × Total cost of cutlet and rasgulla = 2 × (43 + 24) We can write it as = 2 × 43 + 2 × 24 = 46 + 48 = 94
