Please help with this math word problem:

Jamal has a 5X7 picture that he took on his summer vaction and he wants to use a photo copier to enlarge it to an 8X10 picture. To enlarge Jamal has to specify a percent between 50% and 200% on the copier. Explain 2 different ways Jamal can enlarge the picture to make it an 8X10.

Thank you so very much for helping.

  • Math - ,

    You want to increase the width from 5 to 8 which is an increase of 60%
    To prevent distortion, the length would have to be increased by that same percentage, so
    1.60(7) = 11.2
    BUT, we wanted it to be 10, so you will have to crop the picture.
