at a game and hobby store, there are five different chess sets for sale. the least expensive set sells for $10.00 and the most expen-
sive one sells for $59.00. the store owner has arranged the chess sets on the shelf in order from least expensive to most expensive
but he has a problem. he cannot remember the prices of the other three chess sets. he does remember that the price of the third
chess set equals the price of the first and second sets combined. the price of the fourth set equals the price of the second and
third sets combined. the price for the fifth set also follows this rule. each one equals the sum of the prices of the two previous
sets. the store owner figure out the prices of the five chess sets from least expensive to most expensive.

-362

step-by-step explanation:

(12)(4)+2(12)-34(12)+2(12)-3

  \/         \/         \/         \/

  48 +   24 -   408 + 24 - 3

      \   /               \   /

          72     -     432 - 3 = -363

- "runner b is moving at a slower rate."

- "the graphs shown are graphs of distance(km) against time(min).

the slopes of this graphs are are given by:

slope = (change in y)/(change in x)

= (change in distance)/(change in time)

this is the formula for finding the speed. so, the slope of these graphs represent the speed of the runner.

taking each division in the graph to represent 1 on both axis:

runner a ⇒ speed = (2-0)/(1-0)

= 2/1

= 2 km/min

runner b ⇒ speed = (3-0)/(3-0)

= 3/3

= 1 km/min

this shows that   runner b is moving at a slower rate."
