70+80=150
The area of Neil's rooms total
... (10 ft)×(10 ft) + (14 ft)×(14 ft) = 100 ft² +196 ft²
... = 296 ft²
Since Neil will save $1 per square foot by waiting on the sale, he will save
... (296 ft²)×($1/ft²) = $296
Let the number of adults be x, then number of male students is 1 + 7x and the number of female students is (1 + 7x)/2.
x + 1 + 7x + (1 + 7x)/2 = 82
2x + 2 + 14x + 1 + 7x = 164
23x = 164 - 2 - 1 = 161
x = 161/23 = 7
Therefore, number of male students is 1 + 7(7) = 1 + 49 = 50
and the number of female students is 50/2 = 25.
Any natural or whole number works I believe. 1,2,3,4,5,6,7,8,9,10,11etc. Hope this helps
