Betty had $40 in her pocket. she bought 12 identical bags of popcorn. betty was left with $10 after buying the popcorn .what was the price, in dollars, of each bag of popcorn

Each bag of popcorn cost $2.50

$40-$10=30

$30/12=2.5

Hi Mrviral1k,

To solve your problem, you will need to divide and multiply.

So, if we take 40 by 10...

So now we need to take 30 by 12...

So, each bag was $2.50.

Hope this helps!

in problems involving proportions, we can use cross products to test whether two ratios are equal and form a proportion. to find the cross products of a proportion, we multiply the outer terms, called the extremes, and the middle terms, called the means.

hope it

u = -(6/7)w

step-by-step explanation:

place all values with 'u' on one side of the equation.

4u + 8w = - 3u + 2w

4u + 3u = 2w - 8w

further simplify the equation by solving the addition and subtraction.

7u = - 6w

make 'u' the independent variable by placing its co-efficient on the right-hand side.

u = - (6/7)w
