2. Samantha received a loan from the bank for $4,500. She plans on paying off the loan in 4 years. At the end of 4 years, Samantha will have paid
$900 in interest. What is the simple interest rate on the bank loan?

if this is really you s much. i only have 3 points left and i have 2 questions to ask

- "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."
