Answer: " 15 % " .
_______________________________
→ " 12 is <u> 15% </u> of 80 " .
_______________________________
Step-by-step explanation:
_______________________________
12 = (n/100) * 80 ;
12 = (80n) /100 ; Solve for "n:
Note: 80/100 = (80/10) / (100/10) = (8/10) = 0.8 ;
12 = (0.8)n ;
↔ (0.8n) = 12
Multiply each side of the equation by "10" ; to get rid of the "decimal" ;
10 * (0.8n) = 10 * 12 ;
to get:
_______________________________
8n = 120 ;
Divide each side of the equation by "8" ;
to isolate "n" on ONE SIDE of the equation; & to solve for "n" ;
8n/8 = 120/ 8 ;

to get:
_______________________________
n = 15 .

Answer:
Step-by-step explanation:
<u>Let's calculate time for building and testing:</u>
- 5*4 + 15*6 = 110 < 120, yes
- 5*4 + 15*4 = 80 < 100, yes
<u>In general you would need to solve inequalities below:</u>
and
<u>Simplified, we have the system:</u>
