Carolina receives an allowance that is tied to completing her chores during the week. she starts off with an allowance of $20. she has five chores to complete during the week, and for each chore she completes, she receives $3. however, for each chore that is not done by the end of the week, she loses $4 from her allowance.
a. write an expression describing carolina's allowance as a function of the number of chores, c, that she completes during the week.
b. if carolina completes 4 chores, what is her allowance?

4x and 6y

im not sure though

step by step explanation: when u removing the parentheses and combined them that would be : x+3y-x-y=2y

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.
