Mitch is buying candy bars for his friends. he wants to give 2 bars to each friend, and he wants to have 10 spare. he can afford to buy 20 candy bars. what is the algebraic sentence that will him figure out how many friends he can treat? let f= the number of friends pls

Mitch can afford to buy 20 candy bars: (total amount = 20)

He wants to give two bars to each friend. Let friend = f: (2f)

He wants 10 spare bars. Let spare bars = + 10: (+10)

set the equation: total = bars for friends + spare bars.

20 = 2f + 10 is your equation, or (C).

Reason: Isolate friends, f. Note the equal sign, what you do to one side you do to the other. Do the opposite of PEMDAS.

20 = 2f + 10

Subtract 10 from both sides

20 (-10) = 2f + 10 (-10)

10 = 2f

Divide 2 from both sides

10/2 = 2f/2

f = 10/2

f = 5

5 friends in total

hope this helps
