Answer: A quantity grows exponentially when its increase is proportional to what is already there. A common example is compound interest, where $100 invested at 7% per year annual compound interest will double in 10 years. Similarly, if a population grows at 7% per year, it, too, will double in 10 years.
Step-by-step explanation:
$500 < or = $415 + d
(subtract the 415 from both sides)
$85 < or = d
W+d=869
w=d-81
plug in
(d-81)+d=869
2d-81=869
+81 both sides
2d=950
÷2 both sides
d=475
dryer cost $475
let's check w=475-81
w=394
475+394=869
869=869
the solution is true :)
