A local high school held a two-day fundraiser selling lunches. The equations shown represent the amount of money the school collected during the two days.

{
12x + 4y = 152
32x + 12y = 420
12x + 4y = 15232x + 12y = 420

In the equations,
x
x
represents the cost of a chicken lunch and
y
y
represents the cost of a vegetarian lunch. Which is the cost of the vegetarian lunch?

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.
