Q 1. option A......
Q 2. option B....
Step-by-step explanation:
if x is the amount of weekend hours, let y be the amount of weekday hours. then you can solve for x by using the equations x + y = 190 and 49x + 25y = 5275. once you have values for x and y, the other answers should be easy
10% of 450 = 450*(10/100)
= 450 * (1/10)
= 45
final amount = 450 - 45
= 405
