3kg of oranges cost £54. 5kg of apples cost £60. Nina buys 2kg of oranges and 7kg of apples. How much does Nina Pay

First lets start with calculating how much 2kg of oranges cost (we do this by cross multiplying):so if 3kg = £54 2kg = £xto determine the value of x, we can write the following equation:3x = 5423x = 108x = 108/3x = £36.Now we must calculate the cost of buying 7kg of apples. We do this using the same method:5kg = £607kg = £yto determine the value of y, we can write the following equation:5y = 6075y = 420y = 420/5y = £84.Therefore, the total amount Nina pays for 7kg of apples and 2kg of oranges is:total = x + ytotal = £36 + £84total = £120.
