Question

I'am thinking of a number which i then double and add 30. Half the answer is 325. what WAS THE NUMBER i first thought of??/

Answer 1

Answer:

The number you first thought of is 228.75

Step-by-step explanation:

$Half \: the \: answer \: = 325 \\ so \: 325 \div 2 = 162.5 \\ The \: full \: sum \: = 325 + 162.5 = 487.5$

To get the first number you thought of,

$(487.5 - 30)\div 2 \\ = 457.5 \div 2 \\ = 228.75$

Therefore, the answer is 228.75
