Carl Catcher has a batting average of .370, meaning that he makes a hit 37% of the times he is up at bat. Pete Pitcher has a batting averager of only .110. Let x be the number of times Carol comes up to bat and let y be the number of times Pete comes to bat. a. If Carl bats 7 times and Pete bats 3 times, what should ther overall batting average be? b. If a total of 50 times at bat, how many times may Pete bat in order for their combined average to be as close as possible to .300? (define 3 variables, write system and solve)
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

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.
