Answer:
d. $680.
Step-by-step explanation:
Let x be the cost of garage door.
We have been given that the extended warranty on a garage door is $238 and the warranty costs 35% of the purchase price. This means 35% of x equals 238.
We can represent this information in an equation as:
![(35)/(100)x=238](https://img.qammunity.org/2019/formulas/mathematics/high-school/6bwpszax7yssgrawr834ockw2xj0yyxnr4.png)
![0.35x=238](https://img.qammunity.org/2019/formulas/mathematics/high-school/eywnxnju0d5c2js3ty6cehicaz1lnltwxe.png)
![x=(238)/(0.35)](https://img.qammunity.org/2019/formulas/mathematics/high-school/wackhi4ic6a7wla1cbpzdcutbm63qsk3um.png)
Therefore, the cost of garage is $680 and option d is the correct choice.
