3.) Lucille bought 15 mangoes for P225.00, how much will she pay for 25 mangoes at the same rate?​

She will pay P375.00 for mangoes at the same rate.

Step-by-step explanation:

This question is solved by proportions.

Lucille bought 15 mangoes for P225.00

This means that she paid 225/15 = P15.00 for each mangoe.

How much will she pay for 25 mangoes at the same rate?​

25*15 = 375

She will pay P375.00 for mangoes at the same rate.

- "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."
