Step-by-step explanation:

% calculations are totally easy, if you remember to always find and the use 1%.

100% = $2.85

1% = 100%/100 = 2.85/100 = 0.0285

the price difference was

2.91 - 2.85 = $0.06

how many % are these $0.06 compared to yesterday's price ?

that is how many times 1% can fit into this number.

0.06 / 0.0285 = 2.105263158...%

so, rounded this is 2.1%

if you have 89 apples and you take 72 away and buy 14 more and take 12 away then buy 42 more and give them 16 more

Delicious77 [7]

Answer:

The correct answer is that there will be 45 remaining apples.

Step-by-step explanation:

So, you start off with 89 and then you take 72 away, that leaves you with 17 apples. Then, you buy 14 more which brings it up to 31. After that, you give 12 more away which brings your total down to 19. Next, you go out and buy 42 more, which adds up to 61 remaining apples. Finally, you give away 16 more, which brings you to a grand total of, 45 apples left.

Hope this helps!

Multiply the sum of X and Y by 5 and divide the result by the product of two and a

kvv77 [185]

Answer:

$\frac{5(x+y)}{2a}$ or you could write it as 5(x+Y) ÷ 2a

Step-by-step explanation:

So this is a question that kind of uses spoken words rather than numbers and it involves PEMDAS (if you haven't gotten to PEMDAS yet, don't worry about it, it's ok, it's easy). PEMDAS is simply an acronym for Parenthesis, Exponent, Multiply, Divide, Add, Subtract. Its the order in wwhich you do more complicaterd math problems.

Lets break apart the question:

- We have the sum of x and y, we just write that as x+y

- We have that sum multiplied by 5, we have the sum from the step above, now we'll multiply that by 5. 5(x+y) parenthesis means multiply what is outside with what is inside.

- We have the product (multiply) of 2 and a, 2 times a = 2a.

- We divide the x, y, and 5 term with the 2, a term. Take the first part 5(x+y) and divide it by the second part 2a.
