Answer:

Answer:

72.9

Step-by-step explanation:

Fractions method:

81*(90)/(100) because 90/100 is the same thing as 90%

That gives us 7290/100, from 81*90/100

Simplify: =729/10 = 72.9

Decimals method:

81*9 = 729, add in decimal and that's 72.9

Cross-multiplication:

90    100

?         81

This is read as 90 to 100, (as a ratio) so how many to 81? To solve, cross-multiply - 81*90=7290, then divide by 100 to get 72.9.

The Following "Verified" Answer is wrong. On Financial Math the answer is...

C.

$1,285

Answer:

Option C. $1,285 more Dylan need to save.

Step-by-step explanation:

Dylan's essential (fixed) expenses = $900 per month

His essential (flexible) expenses = $400 per month

His non-essential expenses = $295 per month

Total expenses per month = 900 + 400 + 295 = $1595.00

He wants an emergency fund of 3 times monthly living expenses

= $1595 × 3 = $4,785.00

currently, in Dylan's emergency fund account = $3,500

Dylan need to save more = 4,785 - 3,500 = $1,285.00

Dylan need to save $1,285 more to have an adequate emergency fund.
