Answer:
Skiing costs $30 per hour and Boating costs $51 per hour.
Step-by-step explanation:
Let cost per hour of skiing be x and cost per hour of boating be y. Let's dissect the problem into 2 simultaneous equations.
<em><u>"John paid $222 for four hours of skiing and two hours boating":</u></em>

<em><u>"He paid $213 for two hours skiing and three hours boating":</u></em>

<em>Now, if we solve for x in the 2nd equation and plug it in the 1st equation, we will have the value for y</em>. Work shown below.

Hence, y = 51
<em>Now, substituting this y value into the 1st equation and solving for x will give us the value of x.</em>

Hence, skiing costs $30 per hour and boating costs $51 per hour.

Answer:
He brought 3 dozen cookies
She ate
of the bag of Doritos
She read 25 books
Step-by-step explanation:
∵ Mike makes 4 dozen cookies
∵ He brings 75% of them for a party at his school
- Multiply 75% by 4
∵ 75% =
∴ He brought =
× 4
∴ He brought = 3
He brought 3 dozen cookies
∵ Sam bought a bag of Doritos
∵ She ate only 40% of them
∵ 40% = 
∴ She ate =
× 1
∴ She ate = 
She ate
of the bag of Doritos
∵ Jamie took 50 books from the library
∵ She only read half of her whole stack
- Multiply half by 50
∴ She read =
× 50
∴ She read = 25
She read 25 books
