Answer:
Danielle is 7 and her counselor is 21
Step-by-step explanation:
Let x be the age of Danielle and y be the age of her counselor then:
y=3x
x+y=28
We can solve this using substitution. In this case, substitute 3x for y since y=3x...
x+3x=28
4x=28
Divide both sides by 4 (division property of equality)
x=7
y=3x=3(7)=21
Danielle is 7 and her counselor is 21
