The best thing to do is to find 10%, and you can do this by dividing $270 by 10, and therefore, $27 is equal to 10%. To find 40%, you've got to multiply $27 by 4, and this gives you $108. Therefore, gabriel saved $108 last month :)
hope this helps u
To do this problem, you gotta cross-multiply. SO,
multiplied by
12 times 14 = 168
21 times 3 = 63
Then the final answer is
step 1
find the equation of the line
where
x-------> numbers of light bulbs
y-------> the total cost in $
let
A (0,0) B (10,18)
slope m=18/10-----> m=1.8
step 2
with m=1.8 and the point A (0,0)
y-y1=m*(x-x1)------> y=1.8x
step 3
for x=1
y=1.8*1------> y=$1.8
therefore
the answer is
the cost of a single light bulb is $1.8
World population would be: 8,333,078,316
Given:
Each cabinet has 5 drawers.
Each drawer can hold records for 50 clients.
Now,
Each cabinet can hold records for (50 × 5) clients
= 250 clients
Now,
Using unitary method,
250 clients records can be held up in 1 file cabinet.
1 client records can be held up in (1 / 250) file cabinet
600 client records can be held up in (1 / 250) × 600 file cabinet
= 2.4
So, <u>we need 3 file cabinets</u>...cause we cant't get 2.4 file cabinet
