Diophantus of Alexandria, who is known as the father of algebra, lived in Greece about 250 A.D. We know how long he lived by this algebraic riddle that has been passed down over the centuries:
The change is from June, so: vi = 0.9 and v2= unknown f= v2 1 vi = ( f— 1) *100 f= v21 0.9 — 20 = [(v2 / 0.9) — 1)] * 100 v2= [( 20 / 100) + 1] * 0.9 v2 = 0.8 * 0.9 v2= $0.72 million (decrease) July sales would need to be $0,72 million to be 20% less than in June.
Information stored on a hard drive consists of programs and data. The proportion of data storage space to program storage space is 10:1. If the total storage space is 22 megabytes, how much will be allocated to programs and how much to data?
Plot the following equations using only the two data points. First determine the two (x, y) points, then plot and label the points on a coordinate system, and finally draw the equation line between the points. Try one point where x = 0 and another point where y = 0. If these points coincide, pick another (x, y) point.

You are mowing the lawn of a large house. The whole job consists of two parts: the front yard and the back yard. The front takes twice as long as the back. What fraction of the whole job is the back? Use the following notation:
Concrete delivered to a construction site costs $250 a cubic yard. What is the cost of the concrete needed to build a 6-inch-thick patio slab 20 feet by 10 feet?
If bulk candy costs $4.00 a pound and 1 pound fills a box 5 inches by 3 inches by 2 inches, how much will it cost to fill a box 3 inches by 4 inches by 5 inches?
