Homework Help: Math percentage

Posted by kelly on Monday, July 27, 2009 at 6:08pm.

I don't really understand percentages grade 6 math.
1.60% discount on a 7\$ item so items price is 40% of original so 0.4 x 7= 2.8\$?
2. A population of 1500 people increases 15% each year how would this question be done? 1500 x .15=225 so the next years population would be 225 + 1500 is there a faster method.

1.60% discount on a 7\$ item so item's price is 40% of original so 0.4 x 7= 2.8\$?

The original price of an item is \$7.00. Now the store wants to get rid of this item, so it advertises 60% off the original price.

You have two ways of finding out how much you'll pay for this item.

A. 60% of \$7.00 =
0.6 * 7 = \$4.20
\$7.00 = 4.20 = \$2.80

B. 100% - 60% = 40%
40% of 7.00 =
0.4 * 7 = \$2.80

2. A population of 1500 people increases 15% each year how would this question be done? 1500 x .15=225 so the next years population would be 225 + 1500

Yes, that's right.
Another way of solving this to take 115% of 1500.

1.15 * 1500 = 1725
