Step-by-step explanation:
G = (z-s) ÷ r
G × r = (z- s)
Gr + s = z
I think the answer should be 4.7 but rounded up would be 5
we know that
1) You have 
of a pie leftover after your party
2) Each
guest takes home 
of the leftover pie
To find the fraction of the original pie does each guest take home,
Multiply by
so
<u>Simplify </u>
Divide by 
both numerator and denominator
therefore
<u>the answer is</u>
Answer:
27 hours
Step-by-step explanation:
The regular hours are paid normally, 21/hr hence working for 40 hours, Michael earns 40*21=$840
To work x hours paid overtime as 1.5 of the normal rate, the rate would be $21*1.5=$31.5/hr
X hours multiplied by rate of $31.5/hr should be at least equal to $840
31.5x>=840
X>=840/31.5>=26.6667 hours and when rounded off
X is 27 hours
