Answer:
52%
Explanation:
First solve for the remainder:
remainder = 100% - 40%
remainder = 60% since 60% is left after 40% is spent on food.
Now solve for the percent of the total allowance spent:
20% of the remainder =
20% of 60% =
20% * 60% =
20% * 60/100 = ==> 60% = 60/100
1200% / 100 =
12 / 100 = ==> 1200% = 12 * 100%
12 * 100% = 12 * 1 = 12
12 / 100 = 12% spent on transport
Now add up the percent spent on food and the percent spent on transport:
40% + 12% = 52%
