30 students.....14 are boys...that means (30 - 14) = 16 are girls
if 2 boys are dropped......14 - 2 = 12 boys
and 2 girls are added......16 + 2 = 18 girls
fraction of the class that are boys is : 12/30 which reduces to 2/5 <==
Hey there,
So there would be 150 students × by $1.20 per person would be $180.
_______________________________________________________________
→ All that was needed to do was to do 150 students multiplied by the prices of 1.20. That's it! Final answer would be $180.
Final answer $

Hope this helps.

Answer:
There would be 2 answers because it is a quadratic equation
x=4 or x=8
Answer: 7.4
Step-by-step explanation:
3x + 13 = 19
3x = 6
x = 2
Now substitute value of 'x' in the second equation:
2(2) + 1.2(2) + 1
= 4 + 2.4 + 1
= 5 + 2.4
= 7.4
