Answer: ...well can you be a little specific please¿
Step-by-step explanation:
<span> 0.05x + 0.10(35-x) = 2.50
Get rid of decimals by multiplying every term by 100:
5x + 10(35-x) = 250
5x + 350 - 10x = 250
-5x + 350 = 250
-5x = -100
x = 20 = the number of nickels.
The number of dimes is 35-x or 35-20 or 15 dimes.
Checking: 20 nickels is $1.00 and 15 dimes is $1.50
And indeed $1.00 + $1.50 = $2.50
