Answer:
The answer is B
Step-by-step explanation:
The opposite of the opposite of the number is the number itself
-(- turns positive
Number of cookie boxes bought by James = 5
Number of cakes bought by James = 2
Cost of each cakes = $4
Total bill paid by James = $28.50
Let us assume the cost of the each boxes of cookies = x
Then
5x + (2 * 4) = 28.50
5x + 8 = 28.50
5x = 28.50 - 8
5x = 20.50
x = 20.50/5
= 4.10
So we can see from the above deduction that the cost of each boxes of cookies bought by James is $4.10
20. tringle: a+b+c
5x+17+15
5x+32
45-32=5x
13=5x
13÷5=x
2.6 = x
Since 1 is positive, then D would be your answer.
