Sonji has $5.25 in nickels and dimes.The coin value can be modeled by the equation 0.10d + 0.05n = 5.25, where d represents the number of dimes and n represents the number of nickels. If Sonji has 21 dimes, how many nickels does she have? 35 42 63 105


**The answer is 63. If anyone still wants to answer this, go ahead, I'll be generous and give brainiest if you explain well enough.**

Alright so this problem already gave u an equation so all we have to do is plug in value for d and find n.

.10(21) + .05n = 5.25
2.1 + .05n = 5.25
.05n = 3.15
n = 63
I know u already know the answer but it doesn't hurt to still answer and receive a brainiest.
