On her birthday, Ayushi is taking her 5 friends to a movie and treats them with cold drink. The cost of a ticket is ₹150 and a cold drink costs ₹28.50. How much Ayushi has to spend?

Total number of persons = Ayushi + 5 friends = 6

Cost of one ticket = ₹150

Cost of 6 tickets = ₹150 × 6 = ₹900

Cost of one cold drink = ₹28.50

Cost of 6 cold drinks = ₹28.50 × 6 = ₹171.00

Total amount Ayushi has to spend = ₹900 + ₹171

Writing in column form and adding:

$\begin{array}{r} \phantom{+}900.00 \ +\space 171.00 \ \hline 1071.00 \end{array}$

Hence, Ayushi has to spend ₹1,071.
