Option A: 156 + 179 + 25 + 25 = $385
Option B: 334 + 15 + 15 = $364
Option B is cheaper. 10% of $364 is $36.40. That is what you would save with the third option.
X-7/5 = -2
x- 7 = -10
x = -3
The number is -3
Roots stems finite solution
Answer:
The Answer would be C, i think
Step-by-step explanation:
Let the cost of one cup of hot chocolate be = x
Let the cost of one cup of hot tea be = y
Paul paid $ 25.50 for 3 cups of hot chocolate and 4 cups of tea.
Equation becomes = ...(1)
As given, the cost of each cup of tea was 2/3 the cost of each cup of hot chocolate.
.... (2)
Putting the value of y from (2) in (1)
=
=
=
x=4.5
=
y =3
Hence each cup of hot chocolate is $4.50
Each cup of tea is $3.
