10. TBQ - Find the expression for the total cost

Amu, Charan, Madhu, and John went to a hotel and ordered four dosas. Each dosa cost \(₹ ​36​\), and they wish to thank the waiter by tipping \(₹​5​\). Write an expression describing the total cost. 

 

Ans: ​\(36 \times 4 + 5\)\(5 \times 36 + 5\)\(4 \times 5 + 36\)\(36 \times 5 + 5\)​ \(=\) ​

 

If the total number of friends goes up to ​7​ and the tip remains the same, how much will they have to pay? Write an expression for this situation and identify its terms.
