Answer:
The correct options are;
A. 1·2 = 2
B. 1·1 = 1
E. 1 + 1 = 2
Step-by-step explanation:
Given that the equations 1.2 = 2 and 1.1 = 1 are correctly written as 1·2 = 2 and 1·1 = 2, we have;
The product of any number and one is equal the same number, that is a × 1 = a
Whereby we have the expression 1·2 which is 1 × 2, we therefore have;
1 × 2 = 1 · 2= 2
B. Similarly we have;
1 · 1 = 1 × 1 = 1
Also, 1 + 1 = 2 is correct as the sum of two numbers is equal to the sum of the count of the numbers, therefore;
E. 1 + 1 = 2 is correct.

Answer:
15% markup
Step-by-step explanation:
5% markup would be $1. Since 20*5% or 20*.05=1
We can multiply it by 3 to find the percent for $3 markup. Which is 15% or 0.15
Step-by-step explanation:
We observe the line graph.
For every 1 block across, the line goes up by 2 blocks. Therefore Slope = Rise/Run = (2)/(1) = 2.
Also, the y-intercept when x = 0 is 2.
Slope-intercept form: y = mx + c
Hence we have y = 2x + 2. (C)
The answer is 12 ÷ 4 + 13 > 2 + 22 ÷ 2
