Best ResponseYou've already chosen the best response.0if his allowance is x, 3x/5 = allowance on arcade this means that there is 2x/5 remaining 1/3(2x/5) = toy store => 2x/15 = toy store adding 3/5 and 2/15 we get a total amount spent of 11x/15 of his allowances. this must mean that there is only 4x/15 remaining. since his last bit of money was .80, we can say 4x/15 = .80. solving for x we have x = $3.00

Best ResponseYou've already chosen the best response.0because read the question again, he spent 3/5 at the arcade, then he spent 1/3 (emphasis on THIRD) on his REMAINING allowance, not 1/5 of his total allowance, which is why you multiply

Best ResponseYou've already chosen the best response.1let x be the allowance 3/5 of his allowance is 3x/5 (2x/5 is remaining) 1/3 of his remaining is 1/3 of 2x/5 = 2x/15 0.80 is left over the sum of these 3 must add up to the whole allowance \[ \frac{3x}{5} + \frac{2x}{15 }+0.80= x \]

Best ResponseYou've already chosen the best response.1to solve, multiply both sides and all terms by 15 (this will get rid of the fractions) \[ 9x + 2x + 15\cdot 0.8 = 15 x \\ 15 \cdot 0.8 = 4 x\\ x= \frac{15 \cdot 0.8}{4} = 15 \cdot 0.2 = 3.00\]
