... 9田回 =。 = E ▼=▼三EX 8. 16 14. A toy store sells Spinners and Fidget Cubes, the owner pays $4 for spinners and $8 for cubes. One spinner gets a profit of $2 while cubes have a profit of $4. The owner doesn't plan to sell more than 120 toys each month and he doesn't want to buy more than $800 in inventory. How many of each toy should the owner stock to maximize his monthly profit? 1. List the constraints 2. Write the function we are trying to maximize or minimize. 3. Graph the system of inequalities (constraints), use Desmos if this is easier! Don't forget to share your link! 4. Find the vertices 5. Plug values of vertices into the function (step 2) to figure out which combination of spinners and fidget cubes maximizes profits.
Unitary Method
The word “unitary” comes from the word “unit”, which means a single and complete entity. In this method, we find the value of a unit product from the given number of products, and then we solve for the other number of products.
Speed, Time, and Distance
Imagine you and 3 of your friends are planning to go to the playground at 6 in the evening. Your house is one mile away from the playground and one of your friends named Jim must start at 5 pm to reach the playground by walk. The other two friends are 3 miles away.
Profit and Loss
The amount earned or lost on the sale of one or more items is referred to as the profit or loss on that item.
Units and Measurements
Measurements and comparisons are the foundation of science and engineering. We, therefore, need rules that tell us how things are measured and compared. For these measurements and comparisons, we perform certain experiments, and we will need the experiments to set up the devices.
