Question

David buys 2 scones and 2 coffees in a shop and the cost is 18$. ellie buys 3 scones in the same shop and they cost 22$. form two equations and solve to find the cost of each scone and each coffee

Answer 1

Each scone costs $7.33 and each coffee costs $1.67.

Step-by-step explanation:

To find the cost of each scone and coffee, we can form two equations:

Equation 1: 2C + 2S = 18, where C represents the cost of each coffee and S represents the cost of each scone.

Equation 2: 3S = 22

Now let's solve these equations:

From Equation 2, we can find that S = 22/3 = $7.33 (rounded to two decimal places).

Substitute the value of S in Equation 1:

2C + 2(7.33) = 18

2C + 14.66 = 18

2C = 18 - 14.66

2C = 3.34

C = 3.34/2 = $1.67 (rounded to two decimal places).

Therefore, each scone costs $7.33 and each coffee costs $1.67.
