Answer 1

Answer:

fizzy cool is R123.41 and  berry sparks is R92.56

Step-by-step explanation:

ratio = 3+4=7

fizzy cool=$\frac{7}{3} times R52.89 which is equal to R123.41$

berry sparks=$\frac{7}{4}times R52.89 which is equal to R92.56$

Answer 2

Answer:

The ratio of the prices of the fizzy cool and the berry spark is given as 3:4

Let the cost of the fizzy cool be 3$x$ and the cost of berry sparks be 4$x$.

We are supposed to buy 5 fizzy cool soft drinks,

Therefore the total cost of 5 fizzy cool soft drinks= 5 x 3$x$

Total cost = 15$x$

We are supposed to buy 7 berry spark soft drinks,

Therefore the total cost of 7 berry spark soft drinks= 7 x 4$x$

Total cost = 28$x$

The total cost of both the soft drinks = 15$x$ + 28$x$

The total cost is given as Rs. 5,289

15$x$ + 28$x$ = 5,289

43$x$ = 5289

$x$ = 123

Cost of Fizzy cool = 3 x 123= Rs.369

Cost of berry sparks = 4 x 123= Rs.492
