Answer:
27 minutes
Step-by-step explanation:
Given that:
It takes 16 minutes for 9 people to paint 8 walls.
i.e
16 minutes ------------ 9 people ---------- 8 walls
How many minutes does it take 4 people to paint 6 walls?
let the number of minutes be (m). NOW;
(m) minutes ------------ 4 people ------------ 6 walls
If it takes 16 minutes for 9 people to paint 8 walls.
∴ For 1 person to paint 8 walls; it will take 16 minutes × 9 = 144 minutes
So, to determine the number of minutes it will take 1 person to paint 6 walls; we have;
6 walls =
6 walls × 144 minutes = 8 walls × (m)
(m) =
m = 108 minutes
So, it will take 108 minutes for one person to paint 6 walls.
For 4 people now; we have
m =
m= 27 minutes
∴ it will take 27 minutes for 4 people to paint 6 walls
Let the base price be x, cost of tow package be y and cost of hard be z.
So equation for three variables are,
Substract equation x + z = 24890 from equation x + y + z = 25285 to obtain the value of y.
Substract equation x + y = 24290 from x + y + z = 25285 to obtain the value of z.
Substitute the values in the equation x + y +z = 25285 to obtain the value of x.
So base price is $23895, cost of tow package is $395 and cost of hard top is $995.
