Will is 34​% taller than​ Wanda, so​ Will's height is​ ____% of​ Wanda's height.
insens350 [35]
The easiest way for me to do this is too set their heights to actual numbers. Say Wanda is 100 feet tall (which I know isn’t a thing, but 100 is always an easy number for percentages.) If will is 34% taller than 100 feet, 1% is 1 foot, so Will is 134 feet tall. 134 / 100 is 134%, so will’s height is 134% of Wanda/s height. Hope this helps!

Hey there!

To start, first set up your expression like this:
(5x+17)-(3x-4)

You must set up your expression like this since in subtraction, order matters and the problem asks for the difference between the first plant and the second plant, respectively, meaning you must follow in this order.

Now, simplify:
(5x+17)-(3x-4)
(5x+17)+(-3x+4)
2x+21

Therefore, the difference the two companies would be 2x+21.
