Answer:
Jason's weekly allowance is $14.
Step-by-step explanation:
Given:
earnings: 7
total earnings left : 14
weekly allowance = x
cost of movies = x/2
total earnings left 14
less: cash wash earning - 7
allowance after movies 7
divide by: 1/2 ÷1/2
weekly allowance 14
Ebony makes 2000 dollars. She spends 450
so 2000 - 450 = 1550
1550/2000 = 0.775
or .78
100 - 0.78 = 0.22
22% is your answer
hope this helps
We can use PEMDAS to help us:
P - Parenthesis
E - Exponents
M - Multiplication
D - Division
A - Addition
S - Subtraction
PEMDAS states what occurs first in order of which letter pertains to which mathematical operation and how you are suppose to do it from left to right. Since multiplication and division comes before addition and subtraction, we know C isn't the answer since it is subtraction. This leaves us with A, B, and D. They all happen to be either multiplication and division. Although multiplication SEEMS to come before division, multiplication and division are actually paired together (just like addition and subtraction) meaning that if either a multiplication or division comes before a division and multiplication operation, you do it left to right. For example, 2 x 2/2. You do 2 x 2 first equaling 4 and then divide by 2 to get 2. Another example is 10/2 x 5. You DO NOT do multiplication first since multiplication and division are paired together meaning you do 10/2 equaling 5 and then do 5 x 5 equaling 25. Enough explanation for that part. Since 20/4 is the first multiplication/division operation, that is what you do first. The answer is A.
