150(number of tissues)*20(length of tissues) = 3000cm.(total length)
Then to convert it to meters...
1 meter = 100 cm.
3000 ÷ 100 = 30
So 30 meters of paper is needed.
Does that help?
16.75% mark up.
To find this, minus the difference....
23,000 - 19,700 = 3,300..
then divide by the first cost...
23,000 ÷ 3,300 = 0.1675
now multiply that by 100...
0.1675 x 100 = 16.75%
3 parts blue and 2 parts red equals 5 parts. 40 pints divided by 5 parts equals 8. So 3 parts blue x 8 =24 parts blue. 2 parts red is 16 and 24 plus 16 does equal 40
The zeroes are where the graph hits the x axis (left and right)
that ocurs at x=0 and x=5
so answer is A
