Answers:
Katy bought 12 cakes
Gugu bought 36 cakes
Deanna bought 14 cakes
Explanation:
We are given that:
Katy bought x cakes
Gugu bought 3 times as many as Katy. This means that Gugu bought 3x cakes
Deanna bought 2 cakes more than Katy. This means that Deanna bought x+2 cakes
Total number of cakes bought = x + 3x + x + 2 = 5x + 2 cakes
We know that the price of each cake is 85 p = £0.85 and that the total amount paid is <span>£52.7
This means that:
(5x+2)(0.85) = 52.7
4.25x + 1.7 = 52.7
4.25x = 52.7 - 1.7
4.25x = 51
x = 51 / 4.25
x = 12
Now, we will get the number of cakes that each bought as follows:
Katy bought x cakes = 12 cakes
Gugu bought 3x cakes = 3(12) = 36 cakes
Deanna bought x+2 cakes = 12 + 2 = 14 cakes
