8r^6s^3 - 9r^5s^4 + 3r^4s^5 - (2r^4s^5 - 5r^3s^6 - 4r^5s^4) =
8r^6s^3 - 9r^5s^4 + 3r^4s^5 - 2r^4s^5 + 5r^3s^6 + 4r^5s^4 =
8r^6s^3 -5r^5s^4 + r^4s^5 + 5r^3s^6 <==
The equation that relates the number of campers this year to the number of campers last year is c = 440 / 1.10
The number of campers last year is 400.

6 out of 10.
This will be (6/10)×100 = 60%
So, if there are 930 emergency room visits, the expected visits <span>included a prescription for medication is;
</span>
60% of 930 = 60/100 × 930
= 0.6 ×930
= 558
