What is `A_SIMPLE`% of `B_SIMPLE`? (Round to nearest whole number.)

`round((A_SIMPLE * B_SIMPLE) / 100)`

`A_SIMPLE / 100` \times `B_SIMPLE` \approx `round((A_SIMPLE * B_SIMPLE) / 100)`

`B_SIMPLE` is `A_SIMPLE`% of what number? (Round to the hundredths place.)

`round(((B_SIMPLE * 100) / A_SIMPLE) * 100) / 100`

Let `x`

be the number that `B_SIMPLE` is `A_SIMPLE`% of.

`A_SIMPLE / 100` \times x = `B_SIMPLE`

`x=`

`B_SIMPLE`/`A_SIMPLE / 100`

`x \approx`

`round((B_SIMPLE * 100/A_SIMPLE * 100))/100`

`person(1)` has `BANK_MORE` dollars in the bank today. Yesterday, `he(1)` had `BANK_FEWER` dollars in the bank. By what percentage did `person(1)`'s bank account increase over the past day? (Round your answer to the nearest hundredth of a percent.)

`round(((BANK_MORE - BANK_FEWER) * 10000) / BANK_FEWER) / 100`

The bank account grew by

dollars `BANK_MORE` - `BANK_FEWER` = `BANK_MORE - BANK_FEWER`

`\frac{`

`BANK_MORE - BANK_FEWER`}{`BANK_FEWER`} \approx `round(((BANK_MORE - BANK_FEWER) * 10000) / BANK_FEWER) / 100`\%

`person(1)` has `BANK_FEWER` dollars in the bank today. Yesterday, `he(1)` had `BANK_MORE` dollars in the bank. By what percentage did `person(1)`'s bank account decrease over the past day? (Round your answer to the nearest hundredth of a percent.)

`round(((BANK_MORE - BANK_FEWER) * 10000) / BANK_MORE) / 100`

The bank account decreased by

dollars `BANK_MORE` - `BANK_FEWER` = `BANK_MORE - BANK_FEWER`

`\frac{`

`BANK_MORE - BANK_FEWER`}{`BANK_MORE`} \approx `round(((BANK_MORE - BANK_FEWER) * 10000) / BANK_MORE) / 100`\%

`person(1)` has `YEAR_PERCENT_MORE`% more money today than `he(1)` did this time last year. If `person(1)` has `YEAR_THIS` dollars today, how many dollars did `he(1)` have this time last year? (Round to the nearest penny, which is 1/100 of a dollar.)

`YEAR_LAST`

Let `x`

be the amount of money that `he(1)` had last year.

`x + `

`YEAR_PERCENT_MORE / 100`x = `YEAR_THIS`

`(100 + YEAR_PERCENT_MORE) / 100`x = `YEAR_THIS`

`x = \frac{`

`YEAR_THIS`}{`(100 + YEAR_PERCENT_MORE) / 100`}

`x \approx `

`YEAR_LAST`
