To answer the question above, I let x be the number of calendars sold. You may use any other letter as this is just for representation. The total income generated in selling calendars is calculated by multiplying the number of calendars with the price. That is, total income = 5x If we let total income be y, our equation is further simplified into, y = 5x
first we change 2000mm into litres and I think 1000 mm is equals to 1 L then you look at the first digit and in the first number we have for as the first digit the second number 0 the third number two so in this case 0.7 l is the smallest then 2000mm then 4.1 letters
