0.5(20x - 50y + 36) - 0.25(-100x + 40y - 12)
10x - 25y + 18 + 25x - 10y + 3
35x - 35y + 21
Answer:
$8.96
Step-by-step explanation:
To find the total amount, multiply the percentage of the tip (20%) as 0.20 with 7.47
(7.47×0.20=1.494)
Add $1.49 to $7.47
(1.49+7.47=8.96)
And there is your total amount with a 20% tip!
$8.96
80/100 x 30 = 24 because you just multiply percents
