Question

Claire has quarters and nickels in her purse. The total value of the coins is $2.65. Which equation can be used to find x, the number of quarters in Claire’s purse?

Coins in Claire's Purse

Coin - Number of coins
Nickels - 2x +4
Quarters - x

A 5 (2x+4 )+ 25x = 2.65

B 0.05 (2x+4) +0.25x = 2.65

C 0.5 (2x+4) + 0.25x = 2.65

D (2x+4) + x = 2.65

Answer 1

B. 0.05(2x +4) +0.25x =2.65
Reason- The decimals are in the correct places. Its as simples as that. A wouldve been right but it wouldve had to be 265 instead of 2.65
Let me know if I need to explain more (:
