Lets apply that here.
72-[(3x2^3)+48]
So first we start with (3x2^3)
2^3=8
3*8=24
now we do 24+48 which equals 72
now we have 72-72 which equals zero.
So
72-[(3x2^3)+48] = 0
4(9) + 3s = 75
36 + 3s = 75
3s = 39
s = 13
<span>B) Cassie made 100 extra parts yesterday, so she starts the new day with 100 parts. She can make 25 parts an hour.
Here, as we can see graph is starting from 100, so she had that yesterday, & she can make 100/4 = 25 parts an hour.
It is the only answer! Hope this helps!</span>
