WHERE THE ANSWER
Where is the answer??????? I need help. :'(
a. To find the percent of change in the amount of money earned from April to May, we need to compare the difference in the amount of money earned in May to that of April.
First, let's calculate the amount of money earned in April:
Money earned in April = Number of hours in April x Hourly rate = 40 x $6.50 = $260.
Next, let's calculate the amount of money earned in May:
Money earned in May = Number of hours in May x Hourly rate = 32 x $6.50 = $208.
Now, let's find the difference in the amounts earned:
Difference = Money earned in May - Money earned in April = $208 - $260 = -$52.
Since the difference is negative, it indicates a decrease in the amount of money earned.
To find the percent of change, we need to divide the difference by the original amount and then multiply by 100:
Percent of change = (Difference / Money earned in April) x 100 = (-$52 / $260) x 100 = -20%.
Therefore, the percent of change in the amount of money earned from April to May is a decrease of 20%.
b. To find the percent change in the amount of money earned from May to June, we follow a similar process.
First, let's calculate the amount of money earned in May:
Money earned in May = 32 x $6.50 = $208.
Next, let's calculate the amount of money earned in June:
Money earned in June = 42 x $6.50 = $273.
Now, let's find the difference in the amounts earned:
Difference = Money earned in June - Money earned in May = $273 - $208 = $65.
Since the difference is positive, it indicates an increase in the amount of money earned.
To find the percent of change, we need to divide the difference by the original amount and then multiply by 100:
Percent of change = (Difference / Money earned in May) x 100 = ($65 / $208) x 100 ≈ 31.25%.
Therefore, the percent of change in the amount of money earned from May to June is an increase of approximately 31.25%.
c. To compare the percent of change from April to May and May to June, we can simply compare the absolute values of the percentages.
The absolute value of the percent change from April to May is 20%, while the percent change from May to June is approximately 31.25%.
Since 31.25% is greater than 20%, the percent of change from May to June is greater.
Therefore, the greater percent of change is from May to June.
