Sheila went shopping and spent $120 on a coat. she then used 2/3 of the remaining money to buy a dress. she was left with 1/5 of her original amount of money. how much did sheila have at first?

Answer

Find out the how much did Sheila have at first .

To proof

Let us assume that the original amount of money be x .

As given

Sheila went shopping and spent $120 on a coat.

Than

money sheila has =  x - 120

Than the equation becomes

L.C.M of (5,3) = 15

solving

600 +13x = 15x

600 = 15x - 13x

600 = 2x

x = $300

The shelia have money be $300 .

Hence proved

the terms of a geometric sequence can be found by beginning with the first term and multiplying by the common ratio repeatedly. a recursive formula for a geometric sequence with common ratio r is given by an=ran−1 a n = r a n − 1 for n≥2 n ≥ 2 .
