This year, a company produced 8 percent more items than last year. If the company produced 243 items this year, how many items d
Ilya [14]

Answer:

Last year company produce 225 items

Step-by-step explanation:

let the number of items produced last year be x

Here we are asked to find the percent increase in the production of the items from last year  

The production for the last year = x

The production for the current year = 243

Total increased production =243-x

Hence percentage calculation = \frac{\increase \in \sale}{\last \year \sale} \times 100 %

Increased percentage = \frac{243-x}{x} \times 100 %

Percentage increased = 8 %

Hence

\frac{243-x}{x} \times 100 = 8

{243-x}\times 100 = 8 \times x

24300-100x = 8x

24300=100x+8x

24300=108x

x= \frac{24300}{108}

x=225

Hence Last year production was 225 items
