There are 3 car parks, each with 500 spaces in each. There are 150 spaces in a fourth car park.
How many spaces are there altogether?

1650 spaces

Step-by-step explanation: 500 + 500 + 500= 1500 + 150 = 1650

4+n=5

step-by-step explanation:

this is because the four is four hours and the n represents the 1 extra hour over the weekend.

4+n=5 n=1 because if vernon plays 5 hours a week then 4+1=5 hours.
