Answer:
81
Step-by-step explanation:
2(x - 25) = 112
x - 25 = 112/2
x - 25 = 56
x = 56 + 25
x = 81
The supplement of 61 degree is 119 degrees
180-61=119
You need to change 15% to a decimal and multiply it by 25
25 x 0.15 = 3.75
Then add 3.75 to 25 to get the total
25 + 3.75 = 28.75
So, the answer is 28.75$
