Mary and julie both have a goal of raising $1000 for charity. mary raises $12 every 4 days. julie raises $19 every 6 days. will mary or julie reach her goal first? explain.

Julie will reach her goal 21 days before Mary.

Step-by-step explanation:

Mary and Julie both have a goal of raising $1000 for charity.

Mary raises money in every 4 days = $12.

In one day Mary raises money =

                                                = $3

Mary needs time to reach her goal =

                                                          = 333.33  ≈ 334 days

Julie raises money in every 6 days = $19

In one day Julie raises money =

                                                = $3.1666 ≈ $3.2

Julie needs time to reach her goal =

                                                         = 312.5 ≈ 313 days

Difference of the days between both of them to reach their goal

= 334 - 313 = 21 days  

Julie will reach her goal first, 21 days before Mary.

step-by-step explanation:

given the function as;

write the equation replacing f(x) with y

form   and fill a table containing values of y with corresponding values of x

you can take a range for   values of x as -3≤x≤3

solving for x=-3

for x=-2

repeat the same procedure to get the values of y for the remaining ,x=-1 to x=3

plot the values of y against values   of x and obtain the following graph
