Answer:
He spent $ 2.34 in all.
Explanation:
Given,
The amount spent on the bottle of paint = $ 1.89,
While, the amount spent on the brush = $ 0.45,
Hence, the total amount spent = amount spent on paint + amount spent on brush
![= 1.89 + 0.45](https://img.qammunity.org/2020/formulas/mathematics/middle-school/9fsl9m62mnhvniua6ifgfdb4exlac8tebs.png)
