Answer:
217 kids and 264 adults swam at the pool
Step-by-step explanation:
Let
x ----> the number of kids
y ----> the number of adults
we know that
----> equation A
-----> equation B
Solve the system by substitution
substitute equation A in equation B
solve for y
Find the value of x
therefore
6
If 8y+12=36, subtract 36-12=24
Divide 24 by 8 and get three. 2y with y = 3 is 6
13.2855 salt
31÷7 = 4.4285
4.4285 × 3 = 13.2855 salt
