Answer:
p = 2.7x - 20
p(90) = $223
Step-by-step explanation:
revenue → f(x) = 3x ,where x is the number of downloads.
the statement “Your profit p is $20 less than 90% of the revenue for x downloads”

Answer:
<u>10.75%</u>
Step-by-step explanation:
so, you need the total price, which would be 17,850+2,150=20,000 as the whole price of the car, then you need to find what precent 2,150 is of 20,000. then use this formula for finding the precent.
2150/20000 times 100%=10.75%
9=5+1+3
1=3/3
5 and 1/3=5+1/3
9-5 and 1/3=
9-5-1/3=
3+5+1-5-1/3=
3+5-5+1-1/3=
3+5-5+3/3-1/3=
3+0+2/3=
3+2/3=
3 and 2/3
Answer:
x= 23
y=7
Step-by-step explanation:
x-y=16
4y-5=x
4y-5-y=16
3y-5=16 add 5 to both sides
3y=21 divide by 3 on both sides
y=7
x-7=16 substitute back in
x=23 added 7 to both sides
so x=23 and y=7
23-7=16
