1. 3

2. 4

3. 24

Step-by-step explanation:

LCM stands for Least Common Multiple.  A multiple is a number you get when you multiply a number by a whole number (greater than 0). A factor is one of the numbers that multiplies by a whole number to get that number. For example: the multiples of 8 are 8, 16, 24, 32, 40, 48, 56.-

The common multiple for 6 and 8 is 24. That is the Least Common Multiple(LCM)

Part A has true/false questions though that are 8 points.

Part B has multiple choice  questions that are 6 points.

She made the same number points for Part A equal the number of points for part B.

Therefore, 24/8 = 3

So they are 3 true/false questions.

24/6 = 4

So they are 4 multiple choice questions.

In total, they are 7 questions if you include everything.

That is the least number of points for which this was possible.

So each part was 24 points.

Hope it helped!

x= cost per bracelet

number of bracelets * x + shipping charge = total cost

so

9x+9=72
