June has $120.00 in her checking account and she makes a $50.00 deposit in it each week. How much would she have in her account after making a deposit for 3 weeks? AND Is the relationship proportional? Give at least one reason.
$270.00 No. The ratios are not constant. The graph would not start at 0. The equation would not be in y = mx form. There would be a "fee".

Varsha has a pack of multi-colored pens. At the start of each class she selects a blue, black, purple or red pen from the pack at random and replaces it
after class. The table shows the pen color she
selected over the last 16 classes. Is it likely that
there is an equal number of each color pen in the
pack? Explain your reasoning.
No, if there is an equal number of each color pen, each color would be selected about 1/4 of the time (so 4 times each). The range of 1 to 7 implies that it is not likely there is an equal number of each color pen.

If the value of angle 3 is 65, list the other the values of angles 1, 2, 4, 5, and 6 and state the relationships (vocab using complementary, supplementary, and/or vertical) between angle 3 and 4, angle 1 and 4, angle 2 and 5, and angles 1, 2, and 6.
∠1 = 25*, ∠2 = 90*, ∠4 = 25*, ∠5 = 90*, ∠6 = 65*
Relationships:
∠3 and ∠4 are complementary
∠1 & ∠4 are vertical
∠2 & ∠5 are vertical
∠1, ∠2, & ∠6 are supplementary
