--- id: 5d68d631e0696bdec46938f0 title: Part 49 challengeType: 0 --- # --description-- Now that the store and cave locations are complete, we'll code the actions at those locations. Inside the `buyHealth` function, set `gold` to equal `gold` minus 10. For example here is how you would set set `num` to equal 5 less than `num`: `num = num - 5;`. # --hints-- See description above for instructions. ```js buyHealth(), assert(gold === 40); ``` # --seed-- ## --before-user-code-- ```html
