Answer:
Step-by-step explanation:
Let x and y represent the numbers of small and large cars washed, respectively.
We know that:
$4.50x + $8y = $420
But we don't know the relationship between x and y. We need more information (e.g., they washed twice as many small cars and large). Otherwise we have one equation and two unknowns. Since there are two unknowns, we can't determine a "slope" of the line. With all the water and soap, the most we could possibly say it will be a slippery slope.
Answer:
8,4
Step-by-step explanation:
First we need to write the equations for the given scenario. Using the equations, we can form a system of matrix for the situation.
Let the customer buys, x pounds of almonds, y pounds of cashews and z pounds of walnuts. Since he buys 12 pounds of mixed nuts, we can write:
Total cost of these mixed nuts was $118. So we can write:

Customer buys 2 more pounds of walnut than cashews. So, we can write:

Using these equations, we can set up the system of matrix as shown below in the image.
So, the question asks for 64 % of the number 75, which can also be written as:
64%*75.
64% can also be written as a fraction:

so the multiplication will be:

so the answer is 48.
Answer:
<u>The correct answer is 35.4%</u>
Step-by-step explanation:
Let's check the information provided in the question:
Savings goal = US$ 2,000 for the club trip
Earnings for the candles selling = US$ 708
For calculating the accumulated percentage, we can do it this way:
Accumulated percentage = Earnings / Savings goal
Accumulated percentage = 708 / 2,000 * 100
Accumulated percentage = 0.354 * 100
<u>Accumulated percentage = 35.4%</u>
<u>Students at Maple School has accumulated 35.4% of their savings goal with the candles selling.</u>
