What’s the answer to this ? I can’t find it out

The problem is confusing because the words (and question marks) are not consistently used. Let's do this:

... (cooler price) + (tax on the cooler) = (total bill)

The cooler price is 100% of the cooler price.

The tax on the cooler is 6% of the cooler price.

The total bill is the total of these:

... (100% × (cooler price)) + (6% × (cooler price)) = (total bill)

Using the distributive property, we can factor out (cooler price) to get ...

... (100% + 6%) × (cooler price) = (total bill)

Adding the numbers together, we have

... (106%) × (cooler price) = (total bill)

_____

There are two question marks in the addition problem, and each gets a different number. I can't tell from the portion of the picture here what the expected answer is. (I suspect it may be 106%.) I can tell you ...

... 100% of cooler price

... + 6% of cooler price (tax)

... = 106% of cooler price (total bill, $7.95)

== == == == == == == ==

In problems involving retail sales, the term "cost" is usually used to mean the amount the retailer paid his supplier for the item. Here, that term seems to be used interchangeably with the term "price" to refer to the sticker price on the item in the store.

Alexandra purchases two donuts and three cookies at the donut shop and it's charged $3.30. Brianna purchases five donuts and two

Amiraneli [1.4K]

Given:

Cost of two donuts and three cookies = $3.30

Cost of five donuts and two cookies = $4.95

To find:

The cost of each donut.

Solution:

Let x be the cost of each donut and y be the cost of each cookie.

Cost of two donuts and three cookies = $3.30

$2x+3y=3.30$ ...(i)

Cost of five donuts and two cookies = $4.95

$5x+2y=4.95$ ...(ii)

Multiply equation (i) by 2.

$4x+6y=6.60$ ...(iii)

Multiply equation (ii) by 3.

$15x+6y=14.85$ ...(iv)

Subtracting (iii) from (iv), we get

$15x+6y-4x-6y=14.85-6.60$

$11x=8.25$

Divide both sides by 11.

$x=\dfrac{8.25}{11}$

$x=0.75$

Therefore, the cost of each donut is $0.75.
