For the 2013-2014 school year, the cost of tuition at corn university was 43,000 when rounded to the nearest thousand. What is the greatest possible amount the tuition could be? What is the least possible amount the tuition could be?

Greatest possible amount = 43,499

Least possible amount = 42,500

Step-by-step explanation:

Given that :

Cost of tuition rounded to nearest thousand = 43000

Greatest possible amount the tuition could be :

43,499

The value in the hundred place should not exceed 4, because, once it becomes 5 or more, the number will be rounded to 1 and added to 43, which will give 44,000 to the nearest thousand amrather than 43000

Least possible amount the tuition could be :

42,500

For the least amount ; The value in the hundred place should not be below 5 because one, the hundred place value falls below 5, then tuition will be rounded to 42,000 (to the nearest thousand). However, with 42,500, the hundred place value, 5 is rounded to 1 and added to 42 to give 43000 to the nearest thousand.

in problems involving proportions, we can use cross products to test whether two ratios are equal and form a proportion. to find the cross products of a proportion, we multiply the outer terms, called the extremes, and the middle terms, called the means.

step-by-step explanation:

step 1: solve one of the equations for one of the variables. let's solve the first equation for y:

step 2: substitute that equation into the other equation, and solve for x.

step 3: substitute x = 4 x = 4 x=4 into one of the original equations, and solve for y.
