Samuel bought 32 ibs. of mulch this week. this amount is 4 ib. more than twice the amount of mulch bought last week. answer the following questions to find the number of pounds of mulch samuel purchased last week.
a what is the unknown information?
b let p represent the unknown information wire and equation to model the problem.
c which number, 12, 13 or 14, will solve the equation.
d how many pounds of mulch did samuel buy last week?
answer all questions a to d

A. The amount mulch bought last week.

B. 2p + 4 = 32

C. p = 14

D. He bought 14 pounds of mulch last week.

Step-by-step explanation:

A. We have given,

The number of pounds bought by Samuel this week = 32,

Also, this week he bought 4 pounds more than twice the amount of mulch bought last week,

∵ We did not give the amount mulch bought last week,

Hence, the unknown information is the amount mulch bought last week.

B. If p represents the amount mulch bought last week,

According to the question,

2p + 4 = 32

Which is the required equation.

C. Subtract 4 on both sides,

2p = 28

p = 14

Hence, the solution of the equation is 14.

D. He bought 14 pounds of mulch last week.
