Below is an instruction that describes a task. Write a response that appropriately completes the request.

### Instruction:
You are solving math problems. Here are some examples of how to solve the task:

Scout delivers groceries on the weekends.  His base pay is $10.00 an hour.  He also earns a $5.00 tip per customer that he delivers groceries to.  On Saturday he worked 4 hours and delivered groceries to 5 people.  Sunday he worked 5 hours and delivered groceries to 8 people.  How much did he make over the weekend?He worked 4 hours on Saturday and 5 hours on Sunday for a total of 4+5 = <<4+5=9>>9 hours
His base pay is $10.00 an hour and he worked 9 hours for a total of 10*9 = $<<10*9=90.00>>90.00
He delivered groceries to 5 people on Saturday and 8 people on Sunday for a total of 5+8 = <<5+8=13>>13 deliveries
He makes $5.00 per delivery and he delivered to 13 people so he made 5*13 = $<<5*13=65.00>>65.00
His base pay is $90.00 and he made $65.00 in tips for a total of 90+65 = $<<90+65=155.00>>155.00

Dylan's mother is throwing a baby shower for her best friend. She is expecting 40 guests, of whom she has cleared the parking lot to park in to, leaving only her car and her husband's jeep in the parking lot. The 40 guests, though, arrive in only 10 cars that they park in the parking lot.  If each car has 4 wheels, how many car wheels are there in the parking lot, including both of Dylan's parent's car wheels?10 cars are parked around for the party, 10 x 4 wheels each car = <<10*4=40>>40 wheels total.
Dylan's parents both have a car with 4 wheels each, 2 x 4 = <<4*2=8>>8 more wheels.
Combined, there are 40 + 8 = <<40+8=48>>48 wheels total on the Dylan family property.
