A student in COBU260 course scores 60 points out of a possible 110 in the first half of the semester. If there are 140 outstanding points that a student can earn during the second half of the semester, what’s the minimum points out of 140 the student must earn during the second half of the semester to receive a “B” grade (80% final percentage score). Specify your answer as points to be earned during the second half of the semester; do not divide by 140.
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.
Use your knowledge of proportion to solve this problem.
