In Los Angeles, the tax on a property assessed at [tex]\$ 940,000[/tex] is [tex]\$ 13,160[/tex]. Which of the following proportions could you use to find the tax on a property assessed at [tex]\$ 600,000[/tex]?

Select ALL proportions that could work.

[tex]\frac{600000}{x} = \frac{940000}{13160}[/tex]

[tex]\frac{13160}{940000} = \frac{x}{600000}[/tex]

[tex]\frac{13160}{600000} = \frac{940000}{x}[/tex]

[tex]\frac{x}{13160} = \frac{600000}{940000}[/tex]



Answer :

To find the tax on a property assessed at \[tex]$600,000 given that the tax on a property assessed at \$[/tex]940,000 is \[tex]$13,160, we can set up proportions using the relationship between the assessed value and the tax. ### Step-by-Step Solution: 1. Identify the known ratio: The known ratio is: \[ \frac{\text{Tax}}{\text{Assessed Value}} = \frac{13160}{940000} \] 2. Set up the proportion for a property assessed at \$[/tex]600,000:
Let [tex]\( x \)[/tex] be the tax on the property assessed at \$600,000. We need to find the proportions that relate the taxes and assessed values correctly.

3. Evaluate each given proportion:

- First proportion:
[tex]\[ \frac{600000}{x} = \frac{940000}{13160} \][/tex]
Cross-multiplying gives:
[tex]\[ 600000 \times 13160 = 940000 \times x \implies x = \frac{600000 \times 13160}{940000} \][/tex]
This proportion correctly sets up the relationship between the values, so it is valid.

- Second proportion:
[tex]\[ \frac{13160}{940000} = \frac{x}{600000} \][/tex]
Cross-multiplying gives:
[tex]\[ 13160 \times 600000 = 940000 \times x \implies x = \frac{13160 \times 600000}{940000} \][/tex]
This proportion correctly sets up the relationship between the values, so it is valid.

- Third proportion:
[tex]\[ \frac{13160}{600000} = \frac{940000}{x} \][/tex]
Cross-multiplying gives:
[tex]\[ 13160 \times x = 600000 \times 940000 \implies x = \frac{600000 \times 940000}{13160} \][/tex]
Upon inspection, this proportion incorrectly sets up the relationship between the values. It would solve for an incorrect value, so it is not valid.

- Fourth proportion:
[tex]\[ \frac{x}{13160} = \frac{600000}{940000} \][/tex]
Cross-multiplying gives:
[tex]\[ x \times 940000 = 600000 \times 13160 \implies x = \frac{600000 \times 13160}{940000} \][/tex]
This proportion correctly sets up the relationship between the values, so it is valid.

### Conclusion:
The correct proportions are:
[tex]\[ \boxed{\frac{600000}{x} = \frac{940000}{13160}, \ \frac{13160}{940000} = \frac{x}{600000}, \ \frac{x}{13160} = \frac{600000}{940000}} \][/tex]
