Answer:
5000 + (0.16)x > 55,000
Step-by-step explanation:
<u><em>DATA:</em></u>
Michael's salary = $55,000
Cole's basic salary = $5,000
--> Commission = 16% of sales
--> Sales = x
<u><em>Cole's total salary</em></u>
<em>--> Basic salary + Commission x sales</em>
--> 5000 + 16% of x
--> 5000 + (0.16)x as 16 percent is equal to 16/100 = 0.16
<u><em>Cole's total salary should be more than Michael's total salary</em></u>
5000 + (0.16)x > 55000
<em>--> Make x the subject</em>
0.16x > 55000-5000
0.16x > 50,000
x > 50,000/0.16
x > 312500
The inequality that represents the dollar amount of sales is 5000 + (0.16)x > 55000.
The dollar amount of sales that Cole must generate should be more than $312500.
Answer:
3 30 page printers, 10 70 page printers
Step-by-step explanation:
x + y = 13
40x+70y = 820
Solving for y in first equation gives: y = 13 - x
Plug into second equation: 40x + 70(13 - x) = 820
40x + 910 - 70x = 820
-30 x = -90
x = 3
Plug into original equation: 3 + y = 13
y must = 10.
So, the company owns 3 thirty page presses, and 10 70 page presses,
