A team scored 48 points last week and aims for a 50% increase. Estimate first, then choose the new target.

Explicación

Half of 48 is 24, so increasing by 50% gives 48 + 24 = 72 points. The value 48.5 adds the decimal rate as a fixed amount, while 24 is only the added half rather than the new target. The value 98 comes from adding the number 50 instead of taking 50% of 48; 50% of 48 is 24.
