The school held there talent quest and this year they had 1,204 people in attendance. Last year the attendance was only 860. What was the percentage increase from last year?

28.57℅

Step-by-step explanation:

If last year attendance was 860 and the attendance increases to 1204:

Attendance increment = 1204-860

= 344

%increase = increment/current attendance × 100%

% increase = 344/1204 × 100

℅ increase = 34400/1204

% increase = 28.57%

Therefore the percentage increase from last year is 28.57℅

c = 0.429t

step-by-step explanation:

the constant rate at which carlos harvests cassava is 35 minutes per 15 cassavas 15/35 = 0.429 cassava per minute

therefore, an equation that models the number of cassava (c) that harvest carlos in a time (t) is the following:

where t is the time in minutes.

this means that when 35 minutes have elapsed 15 cassava have been harvested, at 70 minutes 30 cassava have been harvested and so on.
