Answer:
34.17
Step-by-step explanation:
8 packs x 4.99/pack=39.92
39.92x.8(100-20% discount)=31.94
31.94 x 1.07% (includes 7% sales tax)=34.17
There are 12 pencils in each packet. 12(3)*20(3)=96
96÷8=12
Answer:
x = 26 2/3
y = 50
Step-by-step explanation:
you could set '2y-3x' equal to '-3x+y+50' because they are vertical angles
2y - 3x = -3x + y + 50
add 3x to each side to get:
2y = y + 50
y = 50
also, we know that (1/2y + 25) + (2y - 3x) = 180 because they form a straight line
3/2y + 25 - 3x = 180
subtract 25 from each side to get:
3/2y - 3x = 155
substitute 50 for 'y' to get:
3/2(50) - 3x = 155
75 - 3x = 155
-3x = 80
x = 26 2/3
