1% = 100 1 50% = 50 ⋅ 100 1 = 100 50 = 2 1 42 + 42 ⋅ 50% = 42 + 4 2 21 ⋅ 2 1 1 = 42 + 21 = 63 A n s w er : n e w am o u n t : 63
You would divide 42 by 2 to find what 50% of the total would be the add that number to 42 to get the answer.
When 42 customers are increased by 50%, the new amount of customers is 63. This is found by calculating 50% of 42, which is 21, and then adding that to the original 42 customers. Thus, 42 + 21 equals 63.
