Diane will spend more than $31 on gifts. So far, she has spent $18. What are the possible additional amounts she will spend? Use c for the additional amount (in dollars) Diane will spend.
Write your answer as an inequality solved for c.

check the picture below.

well, the angle at the vertex d is clearly not a right-angle, let's check for the one at the vertex f which does look like,   however if it's indeed, that means ef is perpendicular to df, in which case their slopes will be negative reciprocal of each other.

so the negative reciprocal of the slope of ef is 1, however the slope of df is not 1, is 1/2, so nope, they're not perpendicular lines.

she was supposed to add the hours(38.5) and multiply the amount of money she earned(7.50) resulting in $288.75 .
