Answer:

7 18-inch wreaths

26 22-inch wreaths

Step-by-step explanation:

Let's say the number of 18-inch wreaths is x and the number of 22-inch wreaths is y.

We know that the number of 22-inch wreaths sold was 5 more than 3 times the number of 18-inch wreaths sold. We can write this into the expression as:

y = 5 + 3x

We also know that each 18-inch wreath was $20 and each 22-inch wreath was $25. The total cost was $790, so:

20x + 25y = 790

Now, let's substitute 5 + 3x in for y in the second equation:

20x + 25y = 790

20x + 25(5 + 3x) = 790

20x + 125 + 75x = 790

95x + 125 = 790

95x = 665

x = 7

Plug this value into y = 5 + 3x to find y:

y = 5 + 3x

y = 5 + 3 * 7 = 5 + 21 = 26

So, 7 18-inch wreaths were sold and 26 22-inch wreaths were sold.

The regular price rounded to the nearest cent
Daniel [21]

Answer:

$189.43

Step-by-step explanation:

To find the original price, write a proportion. In your proportion, write one ration that has sale price over original price. The other ratio should be written with the corresponding percent values. Since the sale price is 65% off then you paid 35% of the regular the price. The proportion should be:

\frac{66.30}{x}= \frac{35}{100}

To solve cross multiply numerator and denominator of each fraction.

66.30(100) = x(35)

6630 = 35x

189.43 = x

This means the regular price is $189.43.

Help anyone please . !!!!
vlabodo [156]

⇒The answer to the first question would be $69.75.

⇒The answer to the 2nd question would be $36.48.

⇒The answer to the 3rd question would be $42.7.

Here's how to get them:

For question 1: A 55% markup for $45 ⇒1.55*45⇒69.75


For question 2: A 60% markup for $22.8⇒ 1.6*22.8⇒36.48


For question 3: A 40% markup for $30.50⇒1.4*30.50⇒42.7

Small Explanation: The reason why there should be a 1 in front of the decimal (which is the percent, but in decimal form) is because by not adding that number 1 in front of the decimal, you will have to do an extra step.


Anyway, hope this helped! :-)
