Joaquin is ordering 5 identical sandwiches and a bag of chips. The bag of chips cost $1.25 and the entire order costs $38.75. Write an equation you can use to find the price of the sandwhich. Let’s represent the price of the sandwhich.

A sandwich costs $7.5

Step-by-step explanation:

Given

Represent chips with c and sandwiches with c

From the question, we understand that 5 sandwiches were ordered.

Hence, the question of the system is:

Substitute values for Total and c

Collect Like Terms

Divide both sides by 5

x= cost per bracelet

number of bracelets * x + shipping charge = total cost

so

9x+9=72

hello from mrbilldoesmath!

answer:   x (x+6)^2, choice b

discussion:

factor x out of the equation:

x^3 + 12x^2 + 36x = x (x^2 + 12x + 36).

note that 6+6 = 12 and 6*6 = 36 so the above factors into:

x (x+6)^2

which is choice b
