Jeff has $25 he spends $10.81 include tax to buy a new dvd. he need to set aside $10 to pay for lunch next week. if peanuts cost $0.38 per package, including tax, what is the maximum number of packages that jeff can buy?

Hey!

First step would be subtract all the money known that he spends from the $25 dollars...

25 - 10 = 15

15 - 10.81 = 4.19

Now with the remaining money you will simply have to use set up an equation..

0.38x = 4.19

Solve for x to get your answer...

4.19/0.38 = 11.03

So Jeff can buy up to 11 packages of peanuts.

11 packages

Hope this Helped!

- "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."
