Julie needs to cut 4 pieces of yarn each with the same length and a piece of yarn 7.75 inches long. let y represents the length of each of the equal pieces of yarn that julie decides to cut. what is the equation that can be used to dectermine the total length of all of the yarn that she ends up cutting, t? is the graph of the equation continuous or discrete?

(a) t=7.75y+4; discrete

(b) t=7.75y+4; continuous

(c) t=4y+7.75; discrete

(d) t=4y+7.75; continuous

You find the equation by traslating the verbal language to algebraic language. 1) 4 pieces of yarn each with length y = > 4y. 2) A piece 7.75 inches long = > add 7.75 to 4y = > 4y + 7.75. 3) Call the total length t = > t = 4y + 7.75. It is a continues function, given that y is a continues variable (it can take any real value). Then the answer is the option (d). t = 4y + 7.75; continuous.
