Answer: this one is confusing
Step-by-step explanation:
Answer:
Total budget last year was $41000
Step-by-step explanation:
The Smiths spend 5% of the total budget on entertainment.
Amount on entertainment = ![\text{Total budget}\times \frac{5}{100}](https://tex.z-dn.net/?f=%5Ctext%7BTotal%20budget%7D%5Ctimes%20%5Cfrac%7B5%7D%7B100%7D)
This year they planned to spend the amount on entertainment = $2150
So, 2150 = Total budget × ![\frac{5}{100}](https://tex.z-dn.net/?f=%5Cfrac%7B5%7D%7B100%7D)
Total budget this year = ![\frac{2150\times 100}{5}](https://tex.z-dn.net/?f=%5Cfrac%7B2150%5Ctimes%20100%7D%7B5%7D)
= $43000
Since, Total budget this year = Total budget last year + $2000
$43000 = Total budget last year + $2000
Total budget last year = $43000 - $2000
= $41000
