Now answer the question:
Khloe and her children went into a grocery store and she bought $6 worth of apples
and bananas. Each apple costs $1.50 and each banana costs $0.30. She bought a total
of 8 apples and bananas altogether. Determine the number of apples, 2, and the
number of bananas, y, that Khloe bought.

Answer:

y = 10

Explanation:

a = apples

b = bananas


the a is equal to 1.5, the b is equal to .3

so it's 2a + xb = 6

(2 x 1.5) + (y x 0.3) = 6

3 + (y x 0.3) = 6

y x 0.3 = 3

so the way we get the answer here, we remove the 0.3 from the side that has the number we're looking for. to do that, we put it on the side with the number we know

with addition problems, you just add or subtract from one side and do the same to the other.

with multiplication, we need to divide one side and multiply by the other.

all the dividing we're doing here will be changing the number with the y to be basically not there

but they'd probably have it written as 0.3y = 3

and the way we sometimes show division, is with the / symbol, so to get this, it would be (0.3y/0.3) = 3 once again, parenthesis just to keep it separate and to try and prevent confusion. you remove the 0.3 from one side and put it on the other by doing the same thing to each side

so it's currently (0.3y/0.3) = 3/0.3s
3 divided by 0.3 comes out to 10

so the answer ends up being y = 10
