• What equation represents the amount if hay, y, she will have left after x days? • Is there another way to represent these functions? If yes, represent each function in another way?
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.
![Explanation:
Gillian has two goats. She feeds them hay and grain.
Gillian buys both kinds of food on April 30. The amount
of grain that Gillian has left, as a function of time,
is modeled by this graph.
Grain Supply
10
3
0 1 2 3 45 6 7 8 9 10
Number of Days Since May 1
Gillian feeds the goats the same amount of hay each
day. On May 3, she has 72 pounds of hay left. On May 5,
she has 60 pounds of hay left.
Based on the information and the graph provided, how
many pounds of hay does Gillian most likely have left
on the day that she most likely has 3 pounds left?
Provide evidence to support your answer.
• What equation represents the amount of grain, y,
she will have left after x day?
• What equation represents the amount if hay, y, she
will have left after x days?
• Is there another way to represent these functions?
If yes, represent each function in another way?
