Answer:
5.35*2+x=16 and the answer is $.35
Step-by-step explanation:
5.35*2+x=16
10.70+x=16
-10.70 -10.70
x=5.30
5.30/15= about .35
Answer:
7.49
Step-by-step explanation:
Well first you have to find how much the bike lock cost.
8.75 x 0.2
1.75 = how much 20% of 8.75 is
8.75-1.75
7 = the cost of the bike lock with the 20% markdown
Now you have to find the sales tax.
7 x 0.07
0.49
7 + 0.49
7.49 = total cost with all the stuff
Hopefully this was helpful. There is a shorter method too tho.
