Baker bakes 5 cinnamon rolls, each 90 cents warm and sweet. But fluffy treats crave creamy friend, 3 icing packs join the bill, grand total to meet. (5(.9)*3) + 3, the answer's in your hand, cinnamon smiles for all the land.
Situation 1: Balancing Budgets at the Bakery
Imagine you're a baker running a small shop. You've just ordered a batch of 5 delicious, fluffy cinnamon rolls that cost $0.90 each. To make them extra special, you also need to buy 3 packages of cream cheese icing, each costing $1.
Expression: 5(0.9x) + 3
5(0.9x): This represents the cost of the cinnamon rolls, with 5 rolls at $0.90 each.
3: This represents the cost of the 3 packages of icing.
So, the expression calculates the total cost of your cinnamon roll supplies: 5(0.9x) + 3. You can plug in the price of each roll ($0.90) into the equation to find the total cost.
Situation 2: Planning a Picnic for Friends
You're planning a picnic for 5 friends and want to bring 3 different types of sandwiches: chicken salad, BLTs, and vegetarian. You decide to make 0.9x sandwiches of each type. To round out the meal, you also buy 3 bags of chips and 3 bottles of juice.
Expression: 5(0.9x) + 3
5(0.9x): This represents the total number of sandwiches, with 5 friends and 3 types of sandwiches at 0.9x each.
3: This represents the number of bags of chips and bottles of juice (3 each).
The expression calculates the total number of food items you'll bring to the picnic: 5(0.9x) + 3. By plugging in the desired number of sandwiches per type (0.9x), you can estimate how much food to prepare for your friends.
These are just two examples of situations where the expression 5(0.9x) + 3 might be used. The beauty of math is that it can be applied to countless real-life scenarios, making it a valuable tool for understanding our world.
