Answer:
1/4x9=9/4 2 1/4, 2.25, (3/2)2
Step-by-step explanation:
The answer is 9/4 when you multiply it. But it can also be simplified as one of the answers here I wrote above.
Let X be the price for a pack of paper
<span>Let Y be the price for a box of pencils. </span>
<span>1) X * 3 packs + Y * 3 boxes = $3.25 </span>
<span>2) X * 2 packs + Y * 1 box = $2.00 </span>
<span>Re-arranging equation 2) gives you Y = ($2.00 - X * 2 packs) / 1 box </span>
<span>Subsitute Y for the Y term in equation X. Multiply through the bracket, collect like terms and solve for X. Then you can use either equation to solve for Y (if you don't get the same answer, you've made a mistake).</span>
Answer: E.G. 70 rounded to the nearest 100 is 100. It rounds up because it is higher than 49, which would round down
500 rounded to the nearest 1000 would be 1000 because it is over 500.
Anything over five will be rounded up (5,6,7,8,9)
Anything under 5 will be rounded down (1,2,3,4)
Hope this helps!
The pricing of the boxes seems to be consistently 2.40 per box. Ethan's cost is
.. 52.80 = 2.40 * (# of boxes)
.. 52.80/2.40 = (# of boxes)
.. 22 = # of boxes
Ethan has bought 22 boxes for 52.80.
