Answer 1

Answer:

$3.00

Step-by-step explanation:

Setting up an equation with a variable and using key words from the problem will allow you to solve for the sum of money.

'x' = sum money

'nine tenths of a sum' = $\frac{9}{10}x$

'is 2.70':  = 2.70

$\frac{9}{10}x$=2.70

Multiply both sides by the reciprocal of 9/10 (10/9):  

(10/9)(9/10)x = 2.70(10/9)

x = 27/9 = $3.00
