Answer:
B
Step-by-step explanation:
To solve this system, solve by substitution.
Rewrite x + y = 24 as x = 24 - y. Substitute it into 3x + 5y = 100.
3(24 - y) + 5y = 100
72 - 3y + 5y = 100
2y = 28
y = 14 5-point questions
Substitute y = 14 back into x = 24 - y and solve for x.
x = 24 - 14
x = 10 3-point questions
