3(-1)+3(0)=-3
-2(-1)+0=2
The answer is the first one
A) N +2 = Q which equals
A) N -Q = -2
B) .05N +.25Q = 3.50 multiplying A) by .25
A) .25N -.25Q = -.5 then adding A) and B)
.30N = 3
Nickels = 10 Quarters = 12
*************DOUBLE CHECK ***************
.05 nickels = $0.50 .25 Quarters = $3.00
12 + 26 + 125 = 163
163 + 0.056(163) = 163 + 9.13 = 172.13
