GIVEN:
Cost of a taco and a cup of tea = $2.10
Cost of 2 tacos and 3 cup of tea = $5.15
ANSWER:
On solving eq(1), we get
Substitute the value of x in eq(2), we get
- 2(2.10 – y) + 3y = 5.15
- 4.20 – 2y + 3y = 5.15
- y = 5.15 – 4.20
- y = 0.95
So, x = 2.10 – 0.95
Hence, Cost of a taco is $1.15
So, <u>Correct choice</u> - [E] $1.15
