Answer:
plug n and r into the equation for the answers.
Step-by-step explanation:
60% of trip = 45 miles
let total trip distance = l
60% is given by multiplying by 0.6
So;
0.6l = 45 \\ \\ l = \frac{45}{0.6} \\ \\ \boxed{l = 75}
Your answer is 75 miles
ANSWER
Three (3) cartons of juice
Y=3X+68.25
80=3X+68.25
Subtract 68.25 from both sides
11.75=3X
Divide
11.75/3=3.91
He can't buy a portion of a juice but he doesn't have enough to buy 4
So he can afford 3 juice cartons
B, because to substitute for a variable you have to have an equation to substitute first.
