Answer:

Explanation:

To add the amounts of paint used, we need to have a common unit of measurement. One way to do this is to express both amounts in terms of a fraction of a gallon. Let's start by expressing 1 gallon as a fraction of a gallon using fraction strips.

We can use a fraction strip with 8 equal parts to represent 1 gallon, so each part represents 1/8 of a gallon.

1 gallon = 8/8

|-------|

1/8 1/8

Now let's express the amount of tan paint Lindsey used in terms of this fraction. Since she used 1 gallon, which is the same as 8/8 of a gallon, we can represent this amount on the fraction strip as follows:

1 gallon = 8/8

|-------|

8/8 0/8

Next, let's express the amount of green paint Lindsey used in terms of this same fraction. She used 43 gallons, so we can represent this amount on the fraction strip as follows:

43 gallons = 344/8

|----------------|

8/8 8/8 ... 8/8 (43 times)

To add these two amounts, we can simply combine the fraction strips by stacking them on top of each other.

1 gallon = 8/8

|-------|

8/8 0/8

43 gallons = 344/8

|----------------|

8/8 8/8 ... 8/8 (43 times)

Total = 352/8

= 44

So Lindsey used a total of 44 gallons of paint.
