GREYUIT [131]

Starts off with 67 people.

Pier two: 67 + 36

103 - 23 = 80

Pier three: 80 + 18

98 - 29 = 69

There will be 69 people on the boat heading for Pier four

Jessica had a bag of candies. She gave 1/8 of her candies to judy. Then jessica gave 3/7 of the candies she had left to Reggie.

AlexFokin [52]

Answer:

Jessica had 32 candies at the beginning.

Step-by-step explanation:

Let the number of candies Jessica had at the beginning be $x$ .

Candies gives to Judy = $\frac{1}{8}x$ .

Now, candies left with Jessica is $x-\frac{1}{8}x=\frac{7x}{8}$ .

Candies given to Reggie is $\frac{3}{7}$ of $\frac{7x}{8}$ .

∴ Candies with Reggie is $\frac{3}{7}\times\frac{7x}{8}=\frac{3x}{8}$ .

Candies left with Jessica after giving to Reggie = $\frac{7x}{8}-\frac{3x}{8}=\frac{4x}{8}$ .

Now, Jessica lost 75% of what she had left. So, 75% of $\frac{4x}{8}$ .

∴ Candies lost = $\frac{75}{100}\times\frac{4x}{8}= \frac{3x}{8}$

Now, candies left with Jessica = $\frac{4x}{8}-\frac{3x}{8}=\frac{x}{8}$ .

As per question,

Candies left with Jessica at last is 4. So,

$\frac{x}{8}=4$

$x=32$

Hence, Jessica had 32 candies at the beginning.
