\n\nOn the basis of the Year 5 profits, a forecast is made for Year 6. It is predicted that Team 1 will increase their profits by 4% while Team 2’s profits will decrease by 4%.
\nWhat will be the forecast for the percentage increase in total profits?
", "advice": "This is quite a complicated calculation, and it is good practice to know how your calculator works especially if you want to use the memory.
\nYear 5 total profit = 45+50 = 95
\n4% increase in Team 1’s profits = 1.04 x 45 = 46.8
\n4% decrease in Team 2’s profits = 0.96 x 50 = 48
\nPredicted profit for Year 6 = 46.8 + 48 = 94.8
