C is your correct answer on this one
Both Andrew and Elena are wrong. The actual value of 2^28 equals 268,435,456.
Step-by-step explanation:
Elena was right when she said exponents mean repeated multiplication but she accidentally calculated the value of 28^2 instead of 2^28. 2^28 means that the number 2 should be multiplied with itself for 28 times.
2^2 means 2 multiplied by 2 equals 4. 2^3 means 2 multiplied by 2 and then multiplied by 2 again which equals 8. Similarly, if you multiply 2 with itself 28 times you will get a value of 268,435,456 (two hundred and sixty-eight million, four hundred and thirty-five thousand, four hundred and fifty-six). So Andrew and Elena will have 268,435,456 coins after 28 days.
Answer: $2.88/16 = $0.18 per ounce. $1.77/10 = $0.177 (rounded $0.18) per ounce. The unit cost for each bag is the same.
Step-by-step explanation:
Divide the cost of each bag by their ounces for the unit cost per bag and then compare each bag to find which bag is more, less, or equal cost.
