Answer: She will pay $64.90 in total.
Step-by-step explanation: The bill at the restaurant comes to $55 and Crystal wants to include an 18% tip.
So you will convert this into decimal form, which will be 0.18.
Now, you will multiply 55 by 0.18, giving you 9.9.
Add that to 55 and you will have your answer.
Have a great day!
If Angel ran a full lap in two minutes, then she ran half of a lap in one minute. If a lap is 2/5 kilometers, the half a lap is 1/5 kilometers.
Step-by-step explanation:
x = father's age now
y = son's age now
x = 2y + 10
x - 20 = 5(y - 20) = 5y - 100
using the first in the second equation :
2y + 10 - 20 = 5y - 100
-10 = 3y - 100
90 = 3y
y = 30
x = 2y + 10 = 2×30 + 10 = 60 + 10 = 70
the father is now 70 years old, the son now 30 years old.
