Answer:
$36.38
Step by step explanation:
First, we need to find out what 1% of $40 dollars is. To do this, we divide 40 by 100.
This gives us $0.40.
To then find out fifteen percent of $40, you then times $0.40 by 15.
This gives us 6 dollars.
Now, to work out the discount, we take 6 from 40.
$40 - $6 = $34
Now we have to work out the tax.
Again, we have to work out what 1% of $34 is.
This gives us $0.34
Then times that by 7 to find 7%
0.34 x 7 = $2.38
Since this is tax we have to add instead of subtracting.
$34 + $2.38 = $36.38 as the final bill.
Answer:
8 pounds of apples.
Step-by-step explanation:
5 pies need 2 pounds of apples.
so 1 pie needs 2/5 pounds
- and 20 pies needs 20 * 2/5
= 40/5
= 8 pounds of apples.
The answer is 3/4.
25% of the 200 jelly beans are green, by converting 25% into a decimal and multiplying it by the total amount of jelly beans, you can find the amount of jelly beans that are green.
25% = 0.25
200 x 0.25 = 50
Therefore 50 of the jelly beans are green.
The question wants to know the probability of the jelly bean being picked is not green.
200 - 50 = 150 jelly beans not green
Finding the probability:
150/200 = 3/4
Answer:
3/4 or 0.75
Step-by-step explanation:
I don’t get all the other stuff but 1/4 + 1/2 = 3/4
