Sally sold seashells by the seashore for 3 days for $2.45 per seashell. On the first day, she sold twice as many seashells as the second day, and on the second day, she sold four seashells less than she sold on the third day. If she sold 7 seashells on the third day, how much money did she make on those three days? seashells less than she sold on the third day. If she sold 7 seashells on the third day, how
much money did she make on those thre

day 3 = 7

day 2 = 7 - 4 = 3

day 1 = 3 * 2 = 6

total seas shells = 7 + 3 + 6 = 16

total money = 16 * 2.45 = $39.20

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!
