Agraphic company charges 560 per hour for the work of its most senior graphic artists, $50 per hour for the work of a production designer, and $18 per hour for the work of a trainee. a recent project required 36 hours of work from a
senior artist, 11 hours from a production designer, and 50 hours from a trainee write out a mathematical statement for calculating the total labor cost, and then compute this cost
select the correct choice below and fill in the answer box to complete your choice
(simplify your answer)
oa. 36 x 560 + 11 x 550 + 50 x 518 = 5
ob. $60-36 +550 - 11 + $18-50 = 5
oc 36x11x50 560 550 x 518 = 5
od. (36 + 11 +50) x (560 + 550 +518) = $

The rate of decay of a radioactive substance depends upon the amount present initially. the mass y (mg) of the radioactive substance cobalt-60 present in a sample at time t (years) is represented by the exponential equation y=50e −0.1315 t . answer the following questions in complete sentences. 1. how does the exponential equation above compare to the equation for simple interest that is compounded continuously? explain the similarities. 2. what is the initial amount of cobalt-60 in the sample? 2. how much cobalt-60 is left after 8.4 years? show your work. 3. what would be the y-intercept of the graph? what does it represent? 4. after how many years will the amount of cobalt-60 left be 6.25 mg? explain what happens to the cobalt-60 after 50 years? 5. discuss some “real-world” examples and uses of cobalt-60
