Answer:
B. 48
100-52 = 48
Step-by-step explanation:
When you are finding the range you are taking the lowest and highest numbers and finding the difference. So you would put the numbers in order from least to greatest then find the highest and lowest amounts.
X-4y=28
8x+4y=8
---------------
9x=36→x=4
4-4y=28→y=6
—-----------------------------------------------------------
y-5=x
4(y-5)-y=4
4y-20-y=4
3y=24
y=8
x8-5=3
Oftentimes, it makes the problem much easier to solve and change into other things like ratios, percentages, and decimals.
Answer:
D*1.2 (OR) 1.2D
Step-by-step explanation:
Because the new menu has one hundred percent of the original menu (D), plus twenty percent, the new menu is 120%, or 1.2
You can then multiply the number of items on the original menu (D), by the new menu's value, which is 1.2 (or 120%).
This brings you to the answer of 1.2D
