The percentage y (of total personal consumption) an individual spends on food is approximately y = 35x -0.25 percentage points (6.5 5 x 5 17.5),
where x is the percentage the individual spends on education. An individual finds that she is spending x = 7 + 0.2t percent of her personal consumption on education, where t is time in months
since January 1. Use direct substitution to express the percentage y as a function of time t (do not simplify the expression). (NOTE: January 1 is represented by t = 0.)
X(t) =
Use the chain rule to estimate how fast the percentage she spends on food is changing on May 1. (Round your answer to two decimal places.)
Specify the units.

$25

step-by-step explanation:

25 - 4.50 = 20.5

20.5 / 2 = 10.25

10.25 + 10 = 20.25

20.25 - 12.50 = 7.75

therefore the answer is $25 as shown as the first number.

i dont have an answer

step-by-step explanation:

$655.61 which is option c

step-by-step explanation:

price of house =   $146,000

initial rate = 3.5%

mortgaged paid in this = 3.5 % of $146,000

                                        =

                                        =$5110

the total years would be = 7

total mortgaged paid = 7 * $5110

                                      =$35770

remaining money = $146000-35770

                                =$110230

new mortgaged payment = 5 % of 110230

                                            =  

                                            =$655.61
