Dani is working a sample booth at the national soda and beverage convention. She is paid $1.50 for each of the first ten tastings $2.50 for each of the next twenty tastings and $4.00 for each tasting beyond thirty she conducts each day. Today Dani conducted 36 tastings. How much total pay did Dani earn today?

She conducted 36 tastings.

10 tastings are in the category of the first 10 tastings.

10 * $1.50 = $15.00

36 - 10 = 26

Out of the remaining 26 tastings, 20 are int eh category of "the next 20 tastings."

20 * $2.50 = $50.00

This accounts for 10 + 20 = 30 tastings.

36 - 30 = 6

She did 6 tastings beyond the 30 tastings, so for the last 6 tastings, she gets paid

6 * $4.00 = $24.00

The total pay is:

$15.00 + $50.00 + $24.00 = $89.00
