Answer:
$300
Step-by-step explanation:
$50-30 = $20 (Amount profited)
$20x5 = $100
$100x3 = $300
167
164<134
134
164+134=298
y equals negative 3 so the answer is -3
I do not understand 1234
3 (8v+5) (8v-5)
192v^2 -75
factor out a 3
3 (64v^2 -25)
now the inside is a difference of squares)
a^2 – b^2 = (a + b)(a – b) where a = 8v and b =5
