300−1.5pTo promote his new business, Claudio made 300 tamales to give to pedestrians. The expression above describes the number of tamales remaining after passing out samples to p pedestrians. If Claudio passed out samples to 160 pedestrians, how many tamales would remain?
Q. 300−1.5pTo promote his new business, Claudio made 300 tamales to give to pedestrians. The expression above describes the number of tamales remaining after passing out samples to p pedestrians. If Claudio passed out samples to 160 pedestrians, how many tamales would remain?
Identify Given Expression: Identify the given expression and the value to substitute.The expression given is 300−1.5p, where p represents the number of pedestrians. We are given that Claudio passed out samples to 160 pedestrians, so we will substitute p with 160.
Substitute Value: Substitute the value of p into the expression.Now we will replace p with 160 in the expression 300−1.5p to calculate the number of tamales remaining.300−1.5(160)
Perform Multiplication: Perform the multiplication part of the expression.We need to multiply 1.5 by 160.1.5×160=240
Subtract Result: Subtract the result from the total number of tamales.Now we subtract 240 from 300 to find the remaining number of tamales.300−240=60
