Answer:
Tom bought a pen for $60 and sold it to gain 20% on his cost price. How much money did he gain?
Solution: CP of the pen = $60.
Gain = 20%.
(SP-CP)*100/CP = Gain %
(SP-60)*100/60 = 20, or
SP-60 = 60*20/100 = 12
SP = 60+12 = $72.
Gain = $72-$60 = $12. Answer.

Answer:
132cm^2
Step-by-step explanation:
first break the shape up into component shapes. the shape is made of two rectangles and two triangles. the area for a rectangle is A=BH where b is base and h is height. the area of a right triangle is BH/2 where b is the base and h is the height. you are given the base and height of the top rectangle 4x7. To find the area of the triangles and the second rectangle you have to do some algebra. the total base length is 19cm and the top rectangle has a length of 7cm so 19-7 leaves you with 12cm to spare and there is two symmetric triangles on each side so 12/2 is 6. now we know all the measurements and can solve.
I believe it is -8 since the point where the line is x=80 and y=-10. Then you divide x/y (80/-10) and get -8.

Answer:
$5
Step-by-step explanation:
If L represents Lisa's earnings, we have ...
$25 = 5L
Dividing both sides of this equation by 5 gives ...
$25/5 = (5L)/5
$5 = L
Lisa earned $5.
