<span>We need to find the correct answer on the given choices:
If a >
0 and b < 0, then The answer is a + b > 0
let’s give a specific example:
let’s have a = 1
and b = .20
</span>
<span>Now,
let’s try calculating if our answer is correct.
Thus a + b > 0
=> a + b
=> 1 + .20
=> 1.20
and 1.20 is greater than 0.
=>Therefore 1.20 > 0 = a + b > 0</span>
I would say to round 48 to 50 and then multiply 50 x 3=150 or if you do 48x3=144 then estimate it to about 140
The correct selling price is about $20, and the likely mistake was the manager multiplied the $12 by .67 (the 67%), got about 8, and took that as the price instead of adding it to the original 12, which is what they were supposed to do.

For each set of ordered pairs, plot the related points on the provided axes. Then use the vertical line test to determine which of the sets is a function. If no vertical line can pass through two or more points in the graph of a relation, then the relation is a function.
