John accepted a reduction of 15% on his salary when his company was not doing well. Now his company's financial position has imp

o-na [289]

To reverse a percentage decrease you divide it by the decrease (+ 100%)
For example we will pick the number, 100, which is decreased by 15% to 85.

To make 85 back to 100 we divide it by the decrease (1-0.15):
85 / 0.85 = 100

To find out how much 85 increased to get back to 100, we do:
15 / 85 = 0.1765 = %17.65

15 is the reduction/difference, and 85 is the with reduction total.

Because percentages stay the same, this is applicable to any numbers, from this, we know that whenever something is reduced by 15% - when restored to it's original is increased by %17.65

The answer is %17.65

Which graph models the solution set of 50x + 150y>1500?

hodyreva [135]

Answer:

see attached diagram

Step-by-step explanation:

First, draw the dashed line 50x+150y=1500 (dashed because the inequality is without notion "or equal to"). You can do it finding x and y intercepts.

When x=0, then 150y=1500, y=10.

When y=0, then 50x=1500, x=30.

Connect points (0,10) and (30,0) to get needed dashed line.

Then determine which region (semiplane) you have to choose. Note that origin's coordinates (0,0) do not satisfy the inequality 50x + 150y>1500, because

$50\cdot 0+150\cdot 0=0$
