Inez is saving money to buy a dress for the homecoming dance. The dress costs $345. She has saved $57 and each week she adds $12 to her savings. How many weeks will it take her to save
enough money to buy the dress?

24 weeks

Step-by-step explanation:

We need to subtract how much she has now from the total cost which gives us 288. then we divide the new cost by the amount she makes a week to get 24. Which makes it so she needs to work for 24 weeks before she can buy the dress.

4 & 3

step-by-step explanation:

factor of 108=2×2×3×3×3=2×2×3^3=the number is 4 because 2 only occurs 2 times and 2×2=4 and factor of 2187=3^3×3^3×3=the number is 3 because 3 onlyvoccur 1 time.
