The amount of money Tom has is 75% of Sally's amount of money. After Sally spent $120 and Tom saved all

his money, Tom's amount of money is 50% more than Sally's. How much money did each have at the

beginning? Use a visual model and a percent line to solve the problem.

Plz help me

- "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."

is there a picture
