Valentina va de compras al mall con $50.000. Gasta 3/5 de esa cantidad en un buzo y la mitad del resto en una falda.¿cuanto dinero le queda a valentina?

The amount left with Valentina is $10,000.

Step-by-step explanation:

The question is:

Valentina goes shopping at the mall with $50,000. She spends 3/5 of that amount on a diver and half the rest on a skirt. How much money does Valentina have left?

The original amount Valentina had was, P = $50,000.

Compute the amount spent on a diver as follows:

D = of $50,000

The amount spent on a diver was, D = $30,000.

Amount left:

A = P - D

   = 50000 - 30000

   = 20000

Compute the amount spent on a skirt as follows:

S = of $20,000

Amount left:

A₁ =  A - S

   = 20000 - 10000

   = 10000

Thus, the amount left with Valentina is $10,000.

- "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."
