8. Evan spent a total of $18 on gourmet jellybeans and chocolate-covered almonds. The jellybeans cost $12/kg. The almonds cost $21/kg. a) Write an equation to represent Evan’s purchases.
b) Isolate the variable for the quantity of jellybeans in your equation.
c) If Evan bought 250 g of almonds, how many grams of jellybeans did he buy?
d) If Evan bought 100 g of almonds, how many grams of jellybeans did he buy?

- "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."

i hope this is what you were looking for.
