Question

You are taking some friends for movie and want to treat them with Pizza. The cost of the movie ticket is $₹120$ and the pizza costs $₹30$. Let $n$ represent the number of friends, then

(a) Write an expression for the total amount you will spend.

(b) if $n=5$, what will be your total expenditure?

Answer 1

Step 1: To find the expression for the total amount.

Given that cost of one movie ticket = $₹120$

So for $n$ friends, total cost = $₹120n$

Since we are not given the number of pizza's ordered, so we assume that number of pizza's ordered = $1$

Money spent on pizza = $₹30$

Thus, the expression for total money spent = $₹120n+30$

Step 2: To find total expenditure when $n=5$.

Now we simply put the value of $n$ in the expression obtained above, we get

$120\left(5\right)+30=₹630$

Thus, the total expenditure = $₹630$.
