Answer:
The correct answer is 5, $10 pens; 1, $3 pen; 94, 50 cents pens.
Step-by-step explanation:
A student has to buy 100 ball point pens and she has $100 to get the job done.
Price of three different pens are $10, $3 and 50 cents or $0.5.
Let the student buy x number of $10 pens and y number of $3 pens. Number of 50 cents pens bought by the student is 100 - x - y. ( x,y
1)
Total amount spent is 10x + 3y + 0.5(100 - x - y) = 100
⇒ 9.5x + 2.5y + 50 = 100
⇒ 1.9x + 0.5y = 10
⇒ 19x + 5y =100
Value of x (in order to hold the equality where both x and y are positive and greater than 1) is 5 and y is 1.
Total number of 50 cents pen bought is 94.
Thus the student buys 5, $10 pens; 1, $3 pen and 94, 50 cents pens.
Answer:
The answer is D the number that is 13 to the right of -4 on the number line.
Step-by-step explanation:
First, you drive 123km per day, and they ask for in a week.
There are 7 days in a week, we have to multiply 123 by 7, which equals 861.
=km per week 861
Now, we need to find out how much cost the gas. Gas cost 1.10 euros per-liter, and this problem wants us to assume that 1euro = 1.26 dollars.
So, we divide 1.10 by 1.26 which is 0.87.
=gas cost 0.87 per liter.
Next, this person goes 31.0 mi/gal per stop.
To get the answer we need to divide 861 the full distance in a week and divide it by how many stops nee to be made which is each 31 mi/gal.
So, 861/31 = 27.77 and now we times 0.87 by 27.77 to get gas cost.
=24.16
