Since we have no information about Kevin's age, let's set that equal to the variable x. So, if Lori is 13 years more than twice the age of Kevin, or x, we would make Lori's age 2x+13. Finally, we would make an equation that proves the sum of both ages equals 49. x+2x+13=49. After solving, we see that x=12, and Lori's age is 37.
Answer:
$39.59
Step-by-step explanation:
37 increase 7% =
37 × (1 + 7%) = 37 × (1 + 0.07) = 39.59
I am assuming Michael's interpretation is correct, that you want to find how much gas is used in 4 days knowing how much is used in 5 days. Set up a simple proportion and solve it:
3/4 tank → 5 days
x tank → 4 days
x = 4 * (3/4) / 5 = 3/5 of a tank
In 4 days you use 3/5 of a tank.
