Answer:
6 years
Step-by-step explanation:
1.75% of 1,200 = 21
so 1 year= 21
21+21= 42 2 years
42+21=63 3 years
63+21=84 4 years
81+21=105 5 years
105+21=126 6 years
Or you can do
21x6=126 so it has to equal 6 years

b=12
Therefore, Tom ordered 12 books
What are your answer choices
Answer:
y=35
Step-by-step explanation:
10(y+7)=12y
10y+70=12y
70=12y-10y
70=2y
70/2=y
35=y
therefore, y=35
A) 85%
To get the percentage you need to do 34/40 to get 0.85. That number is in decimal form and you need to convert it to a percentage. Multiply 0.85 by 100 to get 85 which is your percentage
B) 135%
Same concept as A. Keep in mind that since 54 is greater than 40 the answer should be over 100%
So the math would look like:
54/40 = 1.35
1.35 X 100 = 135%
