Wow this question have just been made easy finally starting to get the hang if it

[LathithaBaninzi]

Shouldn't the answer be up to two decimal places in the exam because my final answer is -20.18.

[Neotshekedi]

the first part of the question, how will you find 20y+45 using the Sum formula?

[tebogobasetsana]

Why was the sum of the second part 360 and not 3048?

[staypositive]
