Answer:
$64.15
Step-by-step explanation:
1.08(99(1-0.4))
99x0.6=59.4
59.4x1.08= 64.152
For how many books he got : 4
This is but adding up 3 of $3.95 to get the total of $11.85
You then want to subtract that from $47.65 to get $34.80
You subtract that by the $8.95 4 times so you see he bought 4 books
After you talk about how many books did he buy after that sentence I’m not sure what your saying
X-intercept is when y=0;
4x-3(0)=12.3
4x=12.3
x=12.3/4
x=3.075 (x-intercept)
y-intercept is when x=0
4(0)-3y=12.3
-3y=12.3
y=12.3/-3
y=-4.1 (y-intercept)
Hope I helped :)
It takes Jack 2 1/4 hours (or 9/4 hours) to complete a project. John takes 3/8 hours longer.
We need to add 9/4 + 3/8
First, make the denominators equivalent.
We can do this by multiplying 2/2 to 7/2 which makes the denominator 8 (since 3/8 is already 8)
9/4 x 2/2 = 28/8
(note that we can do this because 2/2 is 1 and multiplying a number by 1 doesn't change its value)
Add 28/8 + 3/8
28/8 + 3/8 = 31/8
31/8 hours is our final answer, as a mixed number it is 3 7/8 hours :)
