Try 27-12 first.. then add 4
Answer: 4 hours
Step-by-step explanation:
Assume x is the number of hours taken.
Garage A would therefore charge a total of:
= $9 + $1.50 * x
= 9 + 1.50x
Garage B would charge:
= $5 + $2.50 * x
= 5 + 2.50x
To find the number of hours it would take for them to be the same, equate both equations:
9 + 1.50x = 5 + 2.50x
9 - 5 = 2.50x - 1.50x
4 = 1x
x = 4 hours
That cost would be:
= 9 + 1.50 * 4
= 9 + 6
= $15
The answer is B ,, if it's cut into 4 slices so it's equal which you would divide 100 by 4 = 25 :)
Natalie = x
Veronica = 3x
Altogether 4x meaning 4 parts
12 divided by 4 = 3
Natalie got 3 gifts veronica got 9
Another way to work this out is with ratio
1:3 of 12 gifts
1+3 = 4
12 divided by 4 = 3
Each part is 3 gifts
