 Suppose the Central Perk coffee shop sells a cup of espresso for $2.00 and a cup of cappuccino for $2.50. On Friday, Rachel sold 30 more cups of cappuccino than espresso, and she sold $ worth of espresso and cappuccino. How many cups of each were sold? Example #1: Mixture Problem Type 1 ItemAmount SoldCostTotal Cost Espresso Capp.

 Concert Receipts: For a jazz concert, student tickets are $2 each and adult tickets are $4 each. If 200 tickets are sold and the receipts are $750, how many student tickets were sold? ItemAmount SoldCostTotal Cost Student adult Example #2: Mixture Problem Type 1

 Mixing Candies: The owner of a store wants to make a 30 lb. mixture of two candies to sell for $3.00 per lb. If one candy sells for $2.95 per lb. and the other for 3.10 per lb., how many pounds of each should be used? ItemAmount SoldCostTotal Cost Candy 1 Candy 2 MIXTURE

How many pounds of walnuts must be added to 15 pounds of pecans to make a mixture that sells for $1.75 per pound? ItemAmount SoldCostTotal Cost Pecans Walnuts MIXTURE Example #4: Mixture Problem Type 2

 OPPOSITE DIRECTIONS: 2 vehicles traveling in opposite directions – when will they meet?  One car leaves Chicago headed for Cleveland, a distance of 343 miles. At the same time, a 2 nd car leaves Cleveland headed toward Chicago. If the 1 st car averages 50 mph, and the 2 nd car averages 48 mph, how long will it take for the cars to meet? VehicleRateTimeDistance Car 1 Car 2 HINT!! Distance of car 1 + Distance of car 2 = TOTAL DISTANCE Example #5: Distance Problem

 OVERTAKE PROBLEM: two vehicles traveling in SAME DIRECTION – when will one overtake the other?  A cyclist leaves Las Vegas riding at the rate of 18 mph. 1 hour later, a car leaves Vegas going 45 mph in the same direction. How long will it take the car to overtake the cyclist? VehicleRateTimeDistance Cyclist Car HINT!! Distance of car 1 = Distance of car 2 Example #6: Distance Problem
