From the question, we were told that the students earned $708 and they want to make $3710. we are to calculate the percentage they need to achieve the goal.
A percentage is calculated by the product of the ratio of part to the whole and 100 percentage.
So, using the percentage calculation formula:
Percentage = Part x 100%
Whole
So,
Let cost earned by selling candy be S = $708
Let cost required for a club trip be T = $3710
We can then find the percent of earned $708 from total $3710 as follows:
P = S/T x 100%
P = 708 x 100%
3710
P = 354 x 100%
1855
P = 0.19083 x 100%
P = 19.083%
Therefore, P = 19.1%
Hence, 19.1% of their goal has been reached.
