1. Factor by grouping: (16x^2+20x)(20x+25)
2. 4x(4x+5)+5(4x+5)
3. (4x+5)(4x+5)
4. (4x+5)^2
Let x represent milk chocolate bar
y represent creamy nougat bars
3x+4y=4.25
6x+4y=6.5
6x+4y=6.5
-
3x+4y=4.25
=
3x=2.25
x=$0.75
y=$0.5. As a result, one milk chocolate bar costs $0.75 and one creamy nougat bar costs $0.5. Hope it help!
