Answer:

the cost of each sandwich is 5.5

Step-by-step explanation:

we have,

4(x+2) = 30

we know a(b+c) = ab+ac

so, when we open the bracket we get,

4(x+2) = 4x+4*2 which is equal to 4x+8

so, 4x+8 = 30

=> 4x = 30 - 8 [transposing method]

=> 4x = 22

=> x = 22/4

=> x = 5.5

hope this helps
