The number of trees in a rainforest decreases each month by 0.5%. The forest currently has 2.5 billion trees. Write an expression to represent how many trees will be left in 10 years. Then, evaluate the expression.

An expression would be 10(12)-0.005 - 2.5 billion.

Step-by-step explanation:

You can use this expression because if you were to find this problem you would do 10 times 12 because there are 12 months in a year, and the question is talking about 10 years, and then we know that the number of trees decreases by 0.5% , and the forest currently has 2.5 billion trees. Also you can't have a percent into an equation, so I converted it into a decimal by moving the decimal point over to the left twice.

I hope this helps out this is a pretty tricky problem, I tried my best. :)

stew reads at the fastest rate of 265 words per minute.

step-by-step explanation:

it's a given that felicia reads at 260 word per minute and on connie's graph we can see that she reads 200 words per minute. since stew's table tells us that he read 795 in 3 minutes, we can divide 795 by 3 to find out how many words he reads per minute.

795/3 = 265

stew reads 265 words per minute - he reads at the fastest rate since felecia reads at 260 words per minute and connie reads at 200 words per minute.

stew (265) > felecia (260) > connie (200)
