module 06: project option 1

instructions

sarah’s neighbor offers to pay her $5 for every shark tooth she finds on the beach. after collecting only three shark’s teeth, sarah decides to share the opportunity with her friend john. sarah can find shark teeth twice as fast as john, but she can earn even more money with his .

sarah can use the expression 5(2j + 3 + j) to represent the amount of money they can
earn.

part 1: writing expressions

1. write an expression that looks like sarah’s expression: 5(2j + 3 + j). replace the coefficients so that your expression is not equivalent. you may use any number that you choose to replace the coefficients. be sure to leave the variables the same. for example, 8(3j + 7 + 3j) looks like sarah’s expression but is not equivalent.

2. translate the new algebraic expression you created in question 1 to a verbal expression
