The manager of a local discount store reduces the regular retail price of a certain cell phone brand by $3.
a. Use y to represent the regular retail price and write an expression that represents the
discounted price of the cell phone.

b. If 4 of these phones are sold at the reduced price, write an expression in expanded form
(without parentheses) that represents the store's total receipts for the 4 phones.

a. Write an expression that represents the discounted price of the cell phone.
The expression is
(Type an expression using y as the variable. Do not include the $ symbol in your answer.)

a.) y = x - 3

b.)  y = 4x - 12

c.) y = x - 3

Step-by-step explanation:

the answers for a and c are the same, im not sure if they're supposed to be, but that's what its asking

hope this helps :)

he used the algebra tiles correctly.

step-by-step explanation:

given : 3x(2x-1)

solution :

since he used algebra tiles .

armando's solution is the same in the solution shown in figure

as he distributed 2x into x and x and wrote them vertically

and also write   -1 vertically

and 3x into x and x and x and wrote it horizontally

performing the multiplication in the algebra tiles we get

and solving the given expression :

3x(2x-1)

since solving the expression using tiles   and solving the expression algebraically we get the same answer

thus   we can choose the first statement as the answer to this problem which is "he used the algebra tiles correctly".
