Answer:
The final cost after the discount and tax is $179.76
Step-by-step explanation:
Since the discount is 30%, she only pays 70% of the price of the ticket.
Discounted price before tax:
70% of $240 = 0.7 × $240 = $168
Now think of the price $168 as a new price.
The price is $168 which is 100% of the price. Tax is 7% of the price, so you must pay 107% of the price.
107% of $168 = 1.07 × $168 = $179.76
Answer: The final cost after the discount and tax is $179.76
Answer:

Answer:
4a) 135×11/5= 297 miles
b) 216/27= 8 gallons (27miles is the distance one gallon can go)
5) 4+3+4=11
4/11 × x=160
4x=1760
x= 440
6) $4.20/14= $0.3...cereal A
$3.90/12= $0.325...cereal B
Cereal A os the better buy
7) 4×30/3= 40 presents
Hope it's all correct :-)
