1.5 miles/ .6 hours = 2.5 miles per hour
her walking rate is 2.5 miles per hour
d= r * t
4.5 miles = 2.5 * t
divide each side by 3.5
4.5 /2.5 = t
1.8 = t
t = 1.8 hours
11 am - 9 am = 2 hours
She will make it to work on time because 1.8 hours < 2 hours
The price of the fries would be $2.50, the price of the drink would be $2.50, and the price of the cheeseburger wold be $7.50.
We can write a set of equations to represent the prices, if 'f' is fries, 'd' is drink, and 'c' is cheeseburger:
c = 3f
f = d
Using these equations, we can then write out the sum of the items also, as it would be c + f + d = 12.50, but as we know that c = 3f and d = f, we can write it as 3f + f + f = 12.50, and then solve:
3f + f + f = 12.50
5f = 12.50
÷ 5
f = $2.50
Now that we know the price of the fries, we know that the price of the drink is the same, so the drink is also $2.50. Then, we can multiply 2.50 by 3 as we know that the cheeseburger is 3 times the cost of the fries, and 2.50 × 3 = 7.50.
I hope this helps!
The price of the cheeseburger was given in terms of the price of the fries, so let's start by choosing a variable to represent the price of the fries.
Let x = price of fries
Then price of cheeseburger = 3x
Price of drink = x
The cost of the three items is the sum of their prices: x + 3x + x = 5x
The cost is $12.50, so 5x must equal $12.50. That gives us our equation.
5x = 12.5
x = 2.5
The fries and the drink cost $2.50 each.
3x = 3(2.5) = 7.50
The cheeseburger cost $12.50.
Answer: Cheeseburger: $7.50 Fries: $2.50 Drink: $2.50
The most Lana could have charged for each bracelet is $49, assuming she sold one bracelet per day.
Lana earned money over the weekend by selling bracelets. She earned $49 on Friday, $42 on Saturday, and $21 on Sunday. To find the most she could have charged for each bracelet, we should make the assumption that she only sold one bracelet per day, as that would mean she would be earning the maximum per bracelet. Therefore, the most she could have potentially charged for each bracelet would be the highest amount she earned in a day, which was $49.
