Homework Help: Math HELP PLEASE

Posted by Louis on Saturday, January 12, 2013 at 1:33pm.

1.My family went to starbucks. My daughter and myself ordered drinks that were the same price. My son's drink was 5.00 dollars more than my drink. The total bill was $18.50. How much was each drink?

2.There were candies on the table. Andy grabbed 50% of the total candies, Bob grabbed 20% of the total and Cam took only 5% of the total. Now there are only 40 candies left on the table?
how many candies were on the table to begin with?
how many candies did each boy eat?

I was thinking really hard for these 2 questions but to be honest I dont have a clue. I have finished the rest of my homework though. these are the last 2 questions. Please help me . Thanks .

1. Let x = you drink price, then x+5 = your son's.

2x + (x+5) = 18.50

3x = 13.50

x = 4.50

Take it from there.

2. Let x = total number of candies.

x - .5x - .2x - .05x = 40

Solve for x and then the proportions for each person.
