Answer:
75.26
Step-by-step explanation:
Most sales taxes work by not being calculated until cash in some form changes hands. So you take the discount first and then you add the sales tax on the new amount.
Take the discount first
Original cost = 79.74
Discount amount = 79.74 * 12% = 79.74 * 12/100 = 9.57
New price = 79.74 - 9.57 = 70.17
Now you are ready to add on the sales tax
70.17 * 7.25/100 = 5.09
The total is 70.17 + 5.09 = 75.26
Answer:
x=7
Step-by-step explanation
left part + 0.006 = right part + 0.006
----> 0.1x = 0.08x+0.14
left part -0.08x =right part - 0.08x
----> 0.02x=0.14
x=7

Answer:
19 1/18 miles.
Step-by-step explanation:
For Tuesday's ride we need to multiply 10 8/9 by 3/4.
10 8/9 = (9*10+8) / 9 = 98/9 miles.
98 / 9 * 3/4
= 98/3 * 1/4
49/6
= 8 1/6 miles.
Total miles over 2 days = 10 8/9 + 8 1/6
= 18 + 8/9 + 1/6
= 18 + 48/54 + 9/54
= 18 57/54
= 19 3/54
= 19 1/18 miles.
