Bryce goes out for a walk. He walks 9/8 miles
from home. He walks back 1/2 mile before
meeting up with his friend Mya. Write and
simplify an expression (a sum) that describes
this situation.

it will cost dollar $540

the living room is 3 which means if we divide 325/3 then we get $108

therefore if 1part of the living room cost $108 and 3 costed $325

then total 5part of the room will cost 5*108 which gives $540

to determine the unit cost your would divide the total cost by the number sold.

7 bagels for $4.41       $4.41/7 = $.63 each at fresh side

5 bagels for $3.60         $3.60/5 = $.72 each at value mart

80x^8−68x^6+16^5−20x^4−4x^3+8x^2

hope i'm right lol
