Ray should buy the first one because it has the greater volume by 1,440 square inches.
Tank 1: 20x20x18=7,200
Tank 2: 40x12x12=5,760
7,200-5,760=1,440

Arturiano [62]

Answer:

<u>There are 18 girls in a group that has 16 boys.</u>

Step-by-step explanation:

1. Let's review the information given to us for solving the question:

Number of girls in the grade = 81

Number of the boys in the grade = 72

Number of students in the grade = 81 + 72 = 153

2. Let's find the number of girls in a group that has 16 boys.

For getting that number we will use the Rule of three simple, this way:

Number of girls in a group that has 16 boys = (81 * 16)/72

Number of girls in a group that has 16 boys = 1,296 / 72

<u>Number of girls in a group that has 16 boys = 18</u>

<u>There are 18 girls in a group that has 16 boys.</u>
