Carlos spent 1/4 of his money on a toy car. He spent 1/2 of the remainder on a calculator. He had $18 left. How much did he spend altogether?
+307 If he spent 1/2 of the remainder on a calculator then he still has $18. The entire remainder would then be 36 dollars. Because he spent 1/4 of his money, the remainder is 3/4 of his original money. 4/3 x 36 = 48, so he originally had 48 dollars. Because he kept 18 dollars, he spent 30 dollars. As for a bar graph.... a bar graph of what exactly?
