Part a) Create a model for the situation

Let

x------>The number of items that Jane can find in h

we know that

It takes about h for Jane to find item on her shopping list

so

by proportion

Calculate How many items can she find in h

therefore

the answer part a) is

The model for the situation is

Part b) Use your model to find the solution

Solve for x

therefore

the answer part b) is

Part c) State the solution as a full sentence.

the answer Part c) is

It takes about h for Jane to find items on her shopping list

Jane finds a total of  6 items in 3/4 hours.

Step-by-step explanation:

Let x denote the number of items that Jane finds  at a grocery store in the required time.

Now it is given that:

It takes about 1/8 h for Jane to find 1 item on her shopping list.

This means that the time required by Jane to find  'x' items is:  x/8 h

Also, It is 3/4 h before closing time at the grocery store.

This means that the total time to find x items by Jane is equal to 3/4

i.e.

Hence, Jane finds 6 items in her shopping list in 3/4 h.

9 sandwiches per hour
