Mr. Autry bought a hat for $99.90. He also bought a pair of boots for $89.90. What was the total cost of the hat and boots inclu

Pepsi [2]

Answer:

$204.98

Step-by-step explanation:

Step 1: Add both item cost

$99.90 + 89.90 = 189.80$

Step 2: Find the sales tax of the result

$\frac{8}{100}\times 189.8 = 15.184$

Step 1: Convert 8% to fraction
$8\%= \frac{8}{100}$
Simplify
$\frac{8}{100} = \frac{2}{25}$
Step 2: Convert 189.80 to a fraction
$189.80 = \frac{189.8}{1}$
Step 3: Set it up
$\frac{2}{25}\times \frac{189.8}{1}$
Step 4: Cross divide
$189.80 \div 25 = 7.592\\2 \div 1 = 2$
Step 5: Multiply the result
$7.592 \times 2 = 15.184$

Step 3: Add the result from the total cost of both items

$189.80 + 15.184 = 204.98$

The total cost of the hats and boots including sales tax is 204.98 dollars

Jordan and Baylor are baking cookies for the Holidays. Jordan is baking 29 dozen chocolate chip cookies and Baylor is baking 36

Lana71 [14]

Jordan and Baylor are going to have all together 780 cookies

Solution:

Jordan is baking 29 dozen chocolate chip cookies and Baylor is baking 36 dozen sugar cookies.

We have to find how many cookies are they going to have all together?

Now, total number of cookies = cookies made by Jordan + cookies made by Baylor

Total number of cookies = 29 dozens + 36 dozens

Total number of cookies = 65 dozens

Total number of cookies = 65 x 12 per dozen

Total number of cookies = 780

Hence, they altogether have 780 cookies

Yesterday, a movie theater sold 279 bags of popcorn. A large bag of popcorn costs $4. A small bag of popcorn costs $1. In al

Zanzabum

Answer: 4x+y=567, x+y=279, where x=96 and y=183. X represents the large bags and y the small bags

Explanation: We know that our two totals are 279 and 567, so they will be on their own sides of the equation.

The number of large bags (x) plus the number of small bags (y) equals 279 bags in total.

As it relates to price, the price of the large bags (4x) plus the price of the small (y) gives us $567.
