Answer:
$ 7.04
Step-by-step explanation:
The price after two reductions means that we have to multiply the initial price by 25% twice. Remember that 25% is equal to 0.25, because the percentage sign refers to a division by 100. Therefore, the final price after two reductions is $7.04.
The circle graph shows the various percentages of a total of 400 students surveyed.
Those that favored visiting Florida were 38% of the total. Therefore, we have
If 152 of the total 400 students favored visiting Florida, that means the others all put together were 248 students. This means there was 96 more surveyed than those who favored visiting Florida.
Those who favored visiting Florida = 152 surveyed
Those who favored visiting others = 248 surveyed
How many more than favor visiting Florida = 248 - 152
