## Elliott's activity

#### Elliott Fletcher on Calculate density given mass and volume 3 years, 4 months ago

I have begun rewriting the step in order to add the mass/density/volume pyramid, but a custom made pyramid will have to be made in inkscape for this question.

#### Elliott Fletcher on Cumulative percent decrease 3 years, 4 months ago

Saved a checkpoint:

I have rewritten the step so that it includes the variables in the question and gaps asking the student to calculate the decimal multiplier for the decrease and the value after the first month and then after another month.

I have also added a precision hint for the answer in part a).
