Answer:
$2.64
Step-by-step explanation:
9 coins are pennies (reply to my comment if you want to know how I got it)
19 coins are dimes (reply to my comment if you want to know how I got it)
9 (pennies) + 4 = 13 (nickels)
$1.90 (dimes) + $0.09 (pennies) + $0.65 (nickels) = $2.64
9x2=18) 9x3=27) 9x4=36) 9x5=45) 9x6=54) 9x7=63) 9x8=72) 9x9=81) 9x10=90) Multiples of 9. Now it says 9 more than twice a number so you could do like 24 + 24 = 48 + 9 = 57 Now just do that for what ever problem you have just add the numbers together and add 9! Hope this helps! ;D
