Example 5 Irfan bought a pack of biscuits for ₹15 and a packet of toor dal for ₹56. He gave the shopkeeper ₹100. Write an expression that can help us calculate the change Irfan will get back from the shopkeeper. Price for biscuits = Rs 15 Price for toor dal = Rs 56 Total amount he had = Rs 100 Now, Amount he got back = Total Amount – (Price of toor dal + Price of biscuit) = 100 – (56 + 15) Can you calculate how much is this?
