The ratio of staff to patients at Lakeview is 8 to 7. If total staff plus patients is 1575 people,
how many staff are at Lakeview?
help me get started on how to solve this
The ratio of staff to patients is 8:7. The total is 1575.
Add 8+7 = 15, and divide the total by the total of the ratio.
1575/15 = 105
Now multiply 103 by 8 to find the number of staff: 840
Let s = # staff
let p = # patients
s/p = 8/7
Two equations; two unknowns.
