So, from what I'm getting, she needs to cut a 9 2/3 long cloth into 1/3 pieces. You're basically just getting the 9 2/3 and dividing it into 1/3. Your answer would 29 pieces if I'm correct.

Andy has $20 and earns $5 per week selling candy. Jennifer has $50 and earns $2 per week selling chocolate How many weeks until Andy and Jennifer have the same amount of money?

Answers

After 10 weeks, they will have same amount of money.

Step-by-step explanation:

Given,

Amount Andy have = $20

Amount earned per week = $5

Let,

x be the number of weeks.

y be the total cost.

y = 20+5x     Eqn 1

Amount Jennifer have = $50

Amount earned per week = $2

y = 50+2x      Eqn 2

For the same amount of money, the equations will be equal.

Eqn 1 = Eqn 2

Dividing both sides by 3

After 10 weeks, they will have same amount of money.
