Answer:

A. 1.2x = 78

B. x = 65

Step-by-step explanation:

Just informally, first:

x is the number that we don't know. 120% of that number is a number BIGGER than that number. 120% of x is 78. So 78 is BIGGER than the number that we don't know.

120% of x = 78

Change 120% to a decimal by moving the decimal two places to the left. Multiply.

1.2x = 78

To solve, divide both sides by 1.2

x = 78/1.2

x = 65

Answer:

<em>1,760 actual miles separate Springfield from Glenview.</em>

Step-by-step explanation:

<u>Scaling</u>

Objects can be represented in a reduced or augmented size by using scaling which is basically multiplying or dividing real dimensions by a constant factor. We use scaling when representing geographic locations on a map.

The map has the scale:

0.75 inch => 220 miles

This gives us the scaling factor as 220/0.75. There is no need to divide.

We are given the distance from Springfield to Glenview is 6 inches on the map. The actual distance is

6*220/0.75 = 1,760

1,760 actual miles separate Springfield from Glenview.
