Question

A company’s profits this year were 128% of last year’s profits. Drew recorded this year’s profits as 12.8 times last year’s profits. What mistake, if any, did Drew make?

Answer 1

Answer:

The mistake was that 128% is equivalent to 1.28 times last year's profit not 12.8 times

Step-by-step explanation:

we know that

$128\%=128/100=1.28$

Let

x -----> a company’s profits last year

y ----> a company’s profits this year

The company’s profits this year is equal to the company’s profits last year multiplied by 1.28

so

$y=1.28x$

therefore

A company’s profits this year is 1.28 times last year’s profits

The mistake was that 128% is equivalent to 1.28 times last year's profit not 12.8 times
