Answer:
The number of pennies could be 301.
Step-by-step explanation:
First we note that , from the last sentence, the number of pennies must be a multiple of 7.
A good starting point is to find the Lowest Common Multiple of 2,3,5 and 6.
This is 30 and if there's 1 left over after the grouping the answer would be 31 but this cant be right as its not a multiple of 7.
So the number will be of the form 30n + 1 = 7m where n and m are whole numbers.
The only way I can think of solving this is by trial and error. Start with n = 2, then 3 etc , adding 1 then seeing if the result is a multiple of 7.
Grabbing my calculator I'll get going!!! lol!!
Yeah n = 10 fits the bill because 301 is a multiple of 7.
Answer 301.
