12-18.

Chloe wants to place her matrioska dolls in a row on a windowsill that is $92$cm long Will her entire set of $20$dolls fit if their diameters in millimeters are given by the formula $t\left(n\right) = 10 + 3n$?

Graph the series from $t\left(1\right)$ to $t\left(20\right)$.

Rearrange the graph into a single rectangle and find the area.

Is the total less than $92$cm?

Pay careful addition to units. How many millimeters are in a centimeter?
