You have a 4 in. X 6in. family picture that you want to resize. You can choose from a 16 in. X 20 in. or an 18 in. X 24 in. Whic
yarga [219]

Answer:

16 in × 20 in

Step-by-step explanation:

  1. Finding the % of the picture that can fit in 16×20 frame

Area of picture= length by width

                         =4*6=24 in²

Area of frame=Length by width

                      =16*20=320 in²

% of the picture in the frame will be

                        (24/320) * 100% =7.5%

     2. Finding the % of the picture that can fit in 18 × 24 frame

Area of picture=24 in²

Area of frame =Length by width

                       =18*24=432 in²

% of the picture in the frame will be;

                        (24/432)*100%=5.6%

The frame 16 by 20 in will keep 7.5% of the original picture

The frame 18 by 24 in will keep 5.6% of the original picture

Hence you should use the frame  of 16 by 20 in because it will keep more of the original picture.

A bag is on sale for $30. If the sale is 25% off, what was the original price of the bag? Explain your thinking
Eva8 [605]

Answer:

30x25/100

25%=7,5$

30+7,5$=37,5$

The original price was 37,5 because you had to first find out what was 25% in $ to then do the opposite of a sale since we are finding the original price so we have to add it to 30$ since 30$ was the price after the sale.

Hope this helps, have a good day!
