a farmer needs to buy fertilizer for 2 fields. one field is shaped like a trapezoid, and the other is shaped like a triangle. the trapedoidal field has bases that are 35 and 48 yards and a height of 26 yards. the triangular field has the same height as the trapezoidal field and a base of 39 yards. each bag of fertilizer covers 150 square yards. how much fertilizer does the farmer need to buy?

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.
