1. clark has 5 times as many pennies as dimes. If he has a total of 4.29, which two linear equations best model this system? a) P=3D and 0.01P+0.10D=4.29

b) P=3D and 1.10P+0.01D=4.29

c) P+D=3 and 0.01P+0.10D=4.29

d) D=5P and P+D=4.29

2. using the equation from question 1, how many coins does clark have in total?

Tod does not have any cookies. david gives jeff 8 cookies. then he splits half of the cookies he has left with tod. david let’s c represent the number of cookies that he starts with. he finds the number of cookies that tod has is 1/2 the difference of c and 8. write an expression to represent the number of cookies that tod has.
