Rebecca is taking measurements of her window so she can order custom-made blinds online. She discovers her window is 24 1/2 inches by 30 3/8 inches. The website recommends ordering outside-mounted blinds which are 2 percent larger than the window. The site asks for blind measurements in decimals rounded up to the nearest tenth. What size blinds should Rebecca order?
Accepted Solution
A:
we know that
the dimensions of the windows are-------> 24 1/2 in x 30 3/8 in 24 1/2------> (24*2+1)/2-----> 49/2 in 30 3/8-----> (30*8+3)/8-----> 243/8 in
The dimensions 2 percent larger than the window are (49/2)*1.02-----> 24.99 in-------> 25 in 243/8*1.02-----> 30.9825 in-----> 31 in
