Last month the amount on Jaden's bank account statement went from $200 to $150. What was the percent change? (the change is a 25% decrease. Ignore the top half.)

On this month's bank statement, the final balance was $240.

What percent of change was there this month?

answer: i'm great at algebra

step-by-step explanation:

- "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."

not sure but it may be b, as i said i'm not sure.
