As a fraction, 2.161616 is represented as 2 161616/1000000, and when simplified, it becomes 2 10101/62500.

The initial time was 15.7 minutes.

Explanation of steps:

Let x represent the initial time (in minutes).

The relay team is working on minimizing their relay race duration.

First, they cut down their time by 2.1 minutes.

Afterwards, they manage to reduce that time by 10 percent.

If the concluding time ends up being 3.96 minutes, then

x-t1-t2= 3.6
x= 3.6+ t1+ t2
x= 3.6+ 2.1+ 10
x= 15.7

Thus, their starting time was 15.7 minutes.

Response:

Part a) The price of raisins is $0.8 for each ounce

Detailed explanation:

The accurate question is

by using proportions

Determine how many ounces of raisins one can purchase for $1

Let

x -----> the ounces of raisins
