Answer:

x = 0.3

Step-by-step explanation:

6x + 3 + 4x = 1/2 (9 + 10x)

=> 10x + 3 = 1/2 *9 + 5x

=> 5x + 3 = 9 / 2

=> 5x = 9 / 2 -3

=> 5x = (9 - 6) / 2

=> 5x = 3 / 2

=> x = 3 / 10

=> x = 0.3

Hope it helps :)

Answer:

The total price of $4\frac{1}{2}$ pounds of apples is <u>$6.48</u>.

Step-by-step explanation:

Given:

Last week,the price of apples at a grocery store was 1.60 per pound.This week,apples at the same grocery store are on sale for a 10% discount.

Now, to find the total price of 4 1/2 pounds of apples this week at the grocery store.

The price of apples at a grocery store last week was = $1.60 per pound.

This week apples at the same grocery store is on sale of 10% discount.

Thus, the price of apples at a grocery store this week is:

$1.60-10\%\ of\ 1.60.$

$=1.60-\frac{10}{100} \times 1.60$

$=1.60-0.16$

$=\$1.44.$

So, the price of apples per pound this week is $1.44.

Now, to get the total price of $4\frac{1}{2}$ pounds of apples by using unitary method:

If 1 pound of apples cost = $1.44.$

Then, $\frac{9}{2}$ pound of apples cost = $1.44\times \frac{9}{2}$

$=1.44\times 4.5$

$=\$6.48.$

Therefore, the total price of $4\frac{1}{2}$ pounds of apples is $6.48.

We should find the mean number of the tests.
This would be done like: (23+24+25)/3 = 24

After that, you should find the percentage or fraction like this 24/50
Then use the fraction as an estimate like this:

(24/50) * 3250 = 1560

The correct answer is 1560.
