Answer 1

Equation used to find total amount that Sam should pay is x = 23.5(1.18)

Solution:

Given that Sam wants to leave an 18 % tip for his dinner

The bill is for $ 23.50

To find: Equation used to find total amount that Sam should pay

From given question,

tip amount = 18 % of bill

bill amount = $ 23.50

Let "x" be the total amount that Sam should pay

total amount = bill amount + tip amount

x = 23.50 + 18 % of 23.50

$x = 23.50 + 18 \% \text{ of } 23.50\\\\x = 23.50 + \frac{18}{100} \times 23.50\\\\x = 23.50 + 0.18 \times 23.50\\\\x = 23.5 + 0.18 \times 23.5\\\\x = 23.5(1 + 0.18)\\\\x = 23.5(1.18)$

Thus the required equation is x = 23.5(1.18)
