During a week-long dry spell,the water level in a pond decreased by 4 inches per day except for two days when it decreased by half of that amount. How much did the water level decrease in the pond in one week?
4*5 + 2*2

During a week-long dry spell, the water level in a pond decreased by 4 inch. per day,except for 2 days when it decreased by half that amount. How much did the water level decrease in the pond in one week?
Poop+poop
There are 7 days of the week and 2 of those days are gone (hypothetically) which leaves us with 5 days to multiply by the 4 in. which is 20 in. then you have the 2 left over days to multiply by half of 4 (which is also 2) and you get 4 now add together and you have 24 in.
To find out how much the water level decreased in the pond in one week, we need to calculate the decrease for each day and then sum those values.
The water level decreased by 4 inches per day during the dry spell, except for two days when it decreased by half of that amount. So, on those two days, the decrease is 4 / 2 = 2 inches.
Now, let's calculate the decrease for each day:
Day 1: Decrease = 4 inches
Day 2: Decrease = 4 inches
Day 3: Decrease = 2 inches
Day 4: Decrease = 2 inches
Day 5: Decrease = 4 inches
Day 6: Decrease = 4 inches
Day 7: Decrease = 4 inches
To find the total decrease, we add up the values:
Total decrease = 4 + 4 + 2 + 2 + 4 + 4 + 4 = 24 inches
Therefore, the water level in the pond decreased by 24 inches in one week.
