Answer:
P=1440
Step-by-step explanation:
<em>"P is 90 more than Q."</em>
P=Q+90
<em>"20% of P is equal to 1/3 of Q."</em>
1/5(P)=(1/3)Q
From the first equation, we have that P=Q+90.
Thus, we can substitute any P's for Q+90's!
The second equation becomes 1/5(Q+90)=(1/3)Q
Distribute the 1/5 and 1/3 to get (1/5)Q+180=(1/3)Q
Subtract 1/5 Q from both sides.
You should get 180= (2/15)Q
Multiply both sides by 15/2 to get 1350=Q.
Given Q, we can easily solve for P.
Remember the first equation- P=Q+90
Then substitute in 1350 for Q.
So we have P=1350+90
Finally, we have P=1440
Answer:
if the whole (100%) is 50 homes, then half of the whole (50%) is 25 homes. the part of the whole, the homes cleaned, is 15 homes (30%)
so:
50 homes: 100%
25 homes: 50%
15 homes: 30%
