Answer:
a) 10.95
b) 76.65
Step-by-step explanation:
To find the unit price of Ben's video games, divide 43.80 by 4, which is equal to 10.95. So, the unit price is 10.95 at Ben's Game World.
Then, using the unit price we found earlier, multiply 10.95 by 7, which will gives us the cost of 7 games at Roberto's Electronics. You'll get 76.65. So, the cost of 7 games at Roberto's Electronics, using the same unit price at Ben's Game World, would be 76.65.
Hope this helps :)

I agree 26
I’m not that sure but good luck <3
Division. When you divide, the quotient is what you get as the answer
Distributive property or
use FOIL (FOIL is just an acronym to help you remember how to multiply binomials)
distributive property
a(b+c)=ab+ac
(b+c)a=ba+ca
distribute
(-3s+2t)(4s-t)=
(-3s+2t)(4s)+(-3s+2t)(-t)=
(-3s)(4s)+(2t)(4s)+(-3s)(-t)+(2t)(-t)=
-12s^2+8st+3st-2t^2=
-12s^2-2t^2+11st
if you want foil
FOIL (just tells wich terms to multiply)
First
Outer
Inner
Last
exmaple
with
(a+b)(c+d)
First: a times c
Outer: a times d
Inner: b times c
Last: b times d
then add them
(-3s+2t)(4s-t)
First: -3s times 4s=-12s^2
Inner: 2t times 4s=8st
Outer: -3s times -t=3st
Last: 2t times -t=-2t^2
add them
-12s^2+8st+3st-2t^2=
-12s^2+11st-2t^2
