During the last three months of 2015, Apple sold almost 50,000,000 iPhones. A group of students are doing a project and estimate that during the last three months of 2016, Apple will sell about 4\times10^64 × 10 6 iPhones. Which of the following statements is true?

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.
