Multiply the hours worked by the wage,
5x25=125 7x20=140,
Add the two totals,
140+125=265,
Divide total made by hours worked,
$265/12=22.08 dollars an hour.

Answer:
b. 
Step-by-step explanation:
{2m - n = −14
{−m + 3n = 17
⅓[−m + 3n = 17]
{2m - n = −14
{−⅓m + n = 5⅔
____________
1⅔m = −8⅓
____ ____
1⅔ 1⅔
[Plug this back into both equations above to get the n-value of 4]; 
Therefore, our n-value is 4.
