attashe74 [19]

By Pythagoras theorem

$RQ^{2}= x^{2} + 16^{2}$
$RS^{2}= x^{2} + 9^{2}$

$SQ^{2}= RS^{2} + RQ^{2}$
$SQ^{2}= x^{2} + 16^{2} + x^{2} + 9^{2}$
$SQ^{2}=2 x^{2} +256+81$
$25^{2}=2 x^{2} +337$
$625-337=2 x^{2}$

A used-boat dealership buys a boat for $2800 and then sells it for $4000. What is the percent increase?

Rudik [331]

Answer:

Step-by-step explanation:

percent increase = increase divided by original number x 100

increase is the difference between the two numbers...

new number - original number.....4000 - 2800 = 1200

percent increase = (1200 / 2800) x 100

= 0.42857 (round to .4286) x 100

= 42.86 %.....if you need it rounded to the nearest percent, it would be 43% increase
