Question

You are having a party this Weekend and there will be 19 people. You buy 30 packs of glow sticks for 4.51 each and 4 movies for 6.99 each. How much will you have to pay the cashier?

Answer 1

Cost of 1 packet of glow stick = 4.51
Therefore cost of 30 packets of glow sticks = 4.51*30=135.3

Cost of 1 movie = 6.99
Therefore cost of 4 movies = 6.99*4=27.96

Therefore total amount to be paid to the cashier = 135.3+27.96=163.26

Thank you ...

Answer 2

First multiple the no. of glow sticks bought and the cost.
4.51 multiplied by 30=135.30
cost of glow sticks=135.30
Then multiple the no. of movies bought with its cost
6.99 multiplied by 4
cost of 4 movies=27.96
Then add both the answers 
135.30 multiplied by 27.96
Therefore,I have to give 163.26 to the cashier.
