+86 Josh has 90% more pennies than quarters. His combined total is $8.07. How many quarters does he have?
+9519 Does a 'penny' means 0.01 dollar and a 'quarter' means 0.25 dollar?
Just a guess......
Let x be the number of quarter he has.
\(0.25x+0.01(1+90\%)x = 8.07\\ 0.25 x + 0.019 x = 8.07\\ 0.269 x = 8.07\\ 269x = 8070\\ x = 30\)
He has 30 quarters.
Looks like I have guessed correctly of the coins' value!! Yay :D
