Question

Jack’s sister is coming to visit him and parks in the hospital car park.

The bar chart below shows some information about the cars parked in the car park.

How many more white than silver cars are parked in the hospital car park?

Answer 1

lets gather some info...
white cars (level 1) = 230....(level 2) = 120...total of (230 + 120) = 350
silver cars (level 1) = 110....(level 2) = 70...total of (110 + 70) = 180

so there are (350 - 180) = 170 more white cars then silver cars.
