Vanessa is a caterer. She made several batches of appetizers last weekend for an event. This weekend, Vanessa made 4 times as many batches. She made a total of 25 batches of appetizers for the two weekends. Determine the number of batches

Vanessa made last weekend and the number of batches she made this weekend.

Let b = the number of batches of appetizers Vanessa made last weekend.

Answer: Vanessa made 5 batches last weekend and 20 batches this weekend.

Step-by-step explanation:

We have that Vanessa made b batches last weekend, and we know that this weekend she made 4 times as many as the past weekend, so this weekend she made 4*b batches.

In the two weekends, she made a total of 25 batches: this means that:

b + 4*b = 25

5*b = 25

b = 25/5 = 5

then Vanessa made 5 batches last weekend, and 4*5 = 20 batches this weekend.

100 x 13/16 x 25b = 4

18 3/4 = 25b/4

b=25/4

b = 6.25

Step-by-step explanation:

25/4 = 6 1/4 last weekend and 18 3/4 this weekend.
