So lets go step by step, first lets see how much Reagan spent, that is 2 banana splits, $3.25 each, that is:
total spent = 2*3.25 = 6.50
So Reagan spent $6.50 of her weekly allowance, and the problem says that $6.50 represents 26% of her weekly allowance, the question is to find out how much represents the 100% of her weekly allowance.
We can solve this using a rule of three, simple, with direct proportion:
26% -----> $6.50
100% ----> x
x = (100)(6.50)/26 = 650/26
x = 25
therefore Reagan's weekly allowance is $25
Answer:
£500
Step-by-step explanation:
ratio of money = 3 : 1 = 3x : x ( x is a multiplier )
winner receives £250 more than the runner up, that is
3x = x + 250 ( subtract x from both sides )
2x = 250 ( divide both sides by 2 )
x = 125
total prize money = 3x + x = 4x = 4 × 125 = £500
42 and 63 both are at the rate of 2 to 3 and they add up to 105
