Any time you are solving a problem with percentages, use the formula below
% = Is
--- ----
100 Of
Percent over 100 = "is" over "of"
In this case you are solving for percent and the "is" over "of" is $2 / $40
Then you cross multiply and divide.
100 x $2 = $200. 200 divided by 40 = 5. So the answer is 5
Answer:
see explanation
Step-by-step explanation:
These are the first 4 terms of a geometric sequence with n th term
= a₁ 
where a₁ is the first term and r the common ratio
r = 36 ÷ 24 = 54 ÷ 36 = 81 ÷ 54 = 1.5 and a₁ = 24, hence
= 24 
← explicit formula
Answer
39.81
Step-by-step explanation:
First I converted the percent to a decimal which was 0.15
Then I multiplied 0.15 by 34.62 which was 5.193
Lastly I added 5.193 by 34.62 which was 39.813
I rounded it to 39.81

Answer:
2.00 = 0.25(2) +0.10(12) +0.01(23 +p)
Step-by-step explanation:
The number of pennies needed will be the number required to make up the difference between $2.00 and the change already found.
__
Let p represent the number of pennies needed. Together with the change already found, we want the total to be $2.00.
2.00 = 0.25(2) +0.10(12) +0.01(23 +p) . . . . . equation for p
_____
7 pennies need to be found
B is the correct answer :)
