for every 4 adults at the beach one afternoon, there were
3 children. how many children were at the beach if there
were 8, 12, 16, or 20 adults at the beach?
number of adults
number of children

There were 6, 9, 12 and 15 children if the number of adults at the beach were 8, 12, 16 and 20.

Step-by-step explanation:

After reviewing the information given for solving the question, we notice that the number of adults and the number of children are two constants, where the number of children is the 75% of the number of adults (3/4 = 75%). In that case, for finding the number of children for every specific number of adults, we do the following calculations:

1. For 8 adults: Using the 75%, we multiply by it (8 * 75%) and we get that the number of children is 6.

2.  For 12 adults: Using the 75%, we multiply by it (12 * 75%) and we get that the number of children is 9.

3.  For 16 adults: Using the 75%, we multiply by it (16 * 75%) and we get that the number of children is 12.

4.  For 20 adults: Using the 75%, we multiply by it (20 * 75%) and we get that the number of children is 15.

There were 6, 9, 12 and 15 children if the number of adults at the beach were 8, 12, 16 and 20.

go on the tube you might find some information there

the answer is:

the correct option:

b.

to solve the problem, we need to remember how to operate to simplify exponential expressions using the logarithms.

we are given the equation:

then, using placing logarith with base 7 on both sides of the equation, we have:

so, rounding the obtained result to two decimal places (nearest hundreth), we have:

hence, we have that the correct option:

b.

have a nice day!
