Answer:
He can buy 160 crates of apples and 40 crates of pears. (160, 40).
Step-by-step explanation:
From the information given, you can write the following equations:
25x+25y=5000 (1)
6x+5.50y=1180 (2), where:
x is the number of crates of apples
y is the number of crates of pears
First, you can solve for x in (1):
25x=5000-25y
x=(5000/25)-(25y/25)
x=200-y (3)
Then, you can replace (3) in (2) and solve for y:
6(200-y)+5.50y=1180
1200-6y+5.50y=1180
1200-1180=6y-5.50y
20=0.5y
y=20/0.5
y=40
Finally, you can replace the value of y in (3) to find the value of x:
x=200-y
x=200-40
x=160
According to this, the answer is that he can buy 160 crates of apples and 40 crates of pears. (160, 40).
It is a 40.5% increase, how I got my answer.
It is really simple, all I done was added $2,990 and on a caculater started at 100% increase would be 5,980, the reason I started out with 100% is because it is much easyer to judge how much I need to go down or up in percentage, so I knew that I needed to find $4,200, so I moved it down to 45% which equaled $4,335.5 so I brought it down to 41% which equals $4,215.9, so I brought it down to 40% which equals $4,186, then I brought it up to 40.5% which equals $4,200.95, but the .95 does not matter.
I hope this helps!
Answer:
m=5/2
Step-by-step explanation:
the equation of slope is (y2-y1)/(x2-x1)
here are the points given: (0,5), (2,10)
let's label the points:
x1=0
y1=5
x2=2
y2=10
now substitute into the equation (m is the slope)
m=(10-5)/(2-0)
subtract
m=5/2
the slope is 5/2
