Answer:
$39
Step-by-step explanation:
To calculate the total cost of his meal, add the subtotal ($30), the tax on subtotal ($30 X 10%) and the tip ($30 X 20%).
Convert all percentages to decimals to multiply.
Finding tax:
10% = 0.1
Tax = $30 X 0.1 = $3
Finding tip:
20% = 0.2
Tip = $30 X 0.2 = $6
Subtotal + Tax + Tip
= $30 + $3 + $6
= $39
The total cost of his meal was $39.
Answer:
y ≥ 0
Step-by-step explanation:
The way I would do it is by rounding 8.91 up to 9 and I would round 34,871.081 up to 35,000.
9*35,000=315,000
Hopefully I was able to help in some way.
Answer:
C. SA = (1/2)(5)(12) + (1/2)(5)(12) + (5)(2) + (12)(2) + (13)(2)
Step-by-step explanation:
C.
One adult ticket costs £11 and one child ticket costs £8.5
Step-by-step explanation:
Let,
Adult ticket = a
Child ticket = c
According to given statement;
3a+4c=67 Eqn 1
5a+6c=106 Eqn 2
Multiplying Eqn 1 by 5;
Multiplying Eqn 2 by 3;
Subtracting Eqn 4 from Eqn 3
Dividing both sides by 2
Putting c=8.5 in Eqn 1
Dividing both sides by 3;
One adult ticket costs £11 and one child ticket costs £8.5
