A 20 ounce bag of popcorn costs $2.80 at the movie theater, if the unit price remains the same, how much would a 35 ounce bag cost ?
Please help me, I'm in math class and Im stuck.
Use a proportion. Cross multiply and solve for x.
20/2.80 = 35/x
-First find the cost per ounce:
2.80 divided by 20 = .14 per ounce
-Then, multiply by 35 to find the price for 35 ounces:
.14 x 35 = 4.90
-Therefore, a 35 ounce bag of popcorn would be $4.90!
Hope this helped!
n+(-5)
when n=321
it is 4.90
To find out how much a 35 ounce bag of popcorn would cost, you can use a proportion. Let's set up the proportion:
x/35 = $2.80/20
Here, x represents the unknown cost of the 35-ounce bag. To solve this proportion, you can cross-multiply:
20x = 35 * $2.80
Multiply 35 by $2.80:
20x = $98
Now, isolate x by dividing both sides of the equation by 20:
x = $98 / 20
Simplify the division:
x = $4.90
Therefore, a 35-ounce bag of popcorn would cost $4.90.
