Four friends want to take a vacation together, so each one gets a part-time job. each person has 8 weeks to save $720 for the vacation. analyze the four individual plans below and decide which of the four people will reach his or her goal of saving $720 for vacation. friend a: works 13 hours per week at $6.95 per hour. friend b: works 15 hours per week at $5.85 per hour. friend c: works 18 hours per week at $5.25 per hour. friend d: works 11 hours per week at $7.80 per hour.

The friends that reach the goal of saving $720 are Friend A who saved $722.8 and Friend C who saved $756

Explanation:

We need to calculate how much money will they earn according to the time they work and the price of the hour, taking into account that they work for 8 weeks, ando those who have saved more than $720 would have reach their goal.

So for calculating we just need to multiply all the values, first we are going to calculate the total hours and later the total earnings by multiplying it by the price of the hour for each friend:

Friend A worked = 13 hours x 8 weeks = 104 hours

Friend A earned = 104 hours x $6.95 = $722.8

As he gained more than $720 friend A reached the goal.

Friend B worked = 15 hours x 8 weeks = 120 hours

Friend B earned = 120 hours x $5.85 = $702

As he didn't gained more than $720 friend B didn't reached the goal.

Friend C worked = 18 hours x 8 weeks = 144 hours

Friend C earned = 144 hours x $5.25 = $756

As he gained more than $720 friend C reached the goal.

Friend D A worked = 11 hours x 8 weeks = 88 hours

Friend D earned = 88 hours x $7.8 = $686.4

As he didn't gained more than $720 friend D didn't reached the goal.
