The function f(x)=200×1.02^x models the amount of money in jordan's savings account where x represents the number of months since jordan first placed his money into his account which of the following are true statements?
1- the function models exponential growth
2- 200 represents the amount of money jordan put in his savings account in the beginning
3- the rate of decay is 2%
4- jordan has $208.08 after the first month of his savings account
5- at the end of four months, jordan will have more than $220 in savings

let soccer = x and golf = y

part a

1st equation: x + y = 125

2nd equation: x = y +45

part b

replace x in the 1st equation with the 2nd one:

y + 45 + y = 125

simplify:

2y + 45 = 125

subtract 45 from each side:

2y = 80

divide both sides by 2:

y = 80/2

y = 40

she plays golf for 40 minutes.

part c

no because she plays soccer for 45 minutes longer than golf 40 +45 =   85 minutes, not 80 minutes.

step-by-step explanation:

(12)(4)+2(12)-34(12)+2(12)-3

  \/         \/         \/         \/

  48 +   24 -   408 + 24 - 3

          72     -     432 - 3 = -363

the answer is 62.8 cubic units
