Jean's aunt gave her $540 dollars to attend some dance lessons. Every week she pays $25 for a lesson. After some weeks, she still had $315 left.

I think the answer you need is it has been 9 weeks?

Step-by-step explanation:

540-315=225

225/25=9

she has had 9 lessons so far and can afford roughly 12 more

to find the unit price, we must figure out the cost of one item (in this case one dish towel).   to do this, we divide the total price ($7.92) by the number of items bought (for this problem it is 8, because there are eight dish towels in one pack).  

$7.92/8 = $0.99

therefore, the unit price, or the price of one dish towel, is $0.99.

hope this !

the sum of the lengths of any two sides of a triangle is greater than the length of the third side. if you take the three sides of a triangle and add them in pairs, the sum is greater than (not equal to) the third side. if that is not true, then it is not possible to construct a triangle with the given side lengths.
