James supercharges his car which increases his car's speed by 30%. He then cuts weight by 15% which increases the speed a further 10 mph. If his car's original speed was 150 mph what is the new speed?

How fast did James increase his speed? ** He increased his speed by 150*.3=45 mph
How fast is James' car now? ** So his new speed was 150+45=<<150+45=195>>195 mph
How fast is James' car now? ** He increased it a further 10 mph so his new speed is 195+10=<<195+10=205>>205 mph
