One burrito salad costs $8.49 and one tortilla salad costs $3.59
Step-by-step explanation:
Let,
x be the cost of one burrito
y be the cost of one tortilla
According to given statement;
2x+y=20.57 Eqn 1
3x+3y=36.24 Eqn 2
Multiplying Eqn 1 by 3
Subtracting Eqn 2 from Eqn 3
Dividing both sides by 3
Putting x=8.49 in Eqn 1
One burrito salad costs $8.49 and one tortilla salad costs $3.59

Answer:
B
Step-by-step explanation:
The trick you need to employ is that when the rock hits the ground, the timer stops. So h must be taken as 0.
0 = - 16t^2 + 255 Set up the equation
- 255 = - 16t^2 Divide by -16
15.9375 = t^2 Switch
t^2 = 15.9375 Take the square root of both sides.
sqrt(t^2) = sqrt(15.9375)
t = 3.992 seconds
The closest answer is B
