let x be the flour
now
or,(21/2)+x=42/3
or,(21+2x)/2=42/3
or, 3(21+2x)=42×2
or, 63+6x=84
or,6x=84-63
or, 6x =21
or, x=21/6
thus she need 21/6 cups of flour
Answer:
$600
Step-by-step explanation:
Answer:
p=1
Step-by-step explanation:
-7(8-6p)= -6p-8
-56+42p=-6p-8
-56+8=-6p-42p
-48=-48p
1=p
Hope this helps ;) ❤❤❤
L=1.5w
P=l+w
40=2.5 w
W=16
L=1.5(16) =24
Length is 24
Width is 16
Ok so
8000=cost
profit-8000
then
another cost is 15rand per mug
but profit of 35 rand
35-15=20
profit of 20rand per mug
profit=R20m-R8000
where m=number of mugs sold
(R20 means 20 rand)
f(m)=R20m-R8000
break even means cost=earned
basically, when profit=0
0=R20m-R8000
add 8000 to both sides
R8000=R20m
divide both sides by 20
400=m
break even is 400 mugs
graph should be easy enough
put a point at (0,-8000) and at (400,0) then connect them
profit
f(x)=R20x-R8000
break even is 400 mugs
put points (0,-8000) and (400,0) and connect them
