1.29x=21+.99x
You want them to become equal, and you can get that if you get x by itself.
.3x=21
21/.3= 70= x
So at 70 downloads, they'll be the same. We can check to see if we're right.
1.29 ×70=90.3
21 + 69.3 = 90.3
So they'll be the same at 70 downloads, and they'll cost $90.30.
Answer:
Step-by-step explanation:
Given
f(x) = then
f(2) = ( )² = =
Answer:
i) 4x
ii) Father's age = 3(x + 10)
Son's age = x + 10
iii) 4x + 10 = 3(x + 10)
iv) Present age of the son = x = 20
Present age of the father = 4x = 4(20)
= 80
Step-by-step explanation:
Present age of the son = x
Present age of the father = 4x
Age of the son in 10 years = x + 10
Age of the father in 10 years = 3(x + 10)
4x + 10 = 3(x + 10)
4x + 10 = 3x + 30
4x - 3x = 30 - 10
x = 20
The answer would be 120 hope this helps!!
L= Logan's fee per project
E= Evan's fee per project
h= # of hours
T= total cost for both consultants
LOGAN
Add his project fee to his rate per hour ($12) times the number of hours (h)
L= $26 + $12h
EVAN
E= $36 + $15h
TOTAL COST FOR BOTH
Add the two equations above together for total cost for both consultants
T= ($26 + $12h) + ($36 + $15h)
combine like terms
T= ($26 + $36) + ( $12h + $15h)
T= $62 + $27h
ANSWER: T= $62 + $27h; the two consultants would be paid a $62 project fee plus $27 per hour.
Hope this helps! :)
