Answer:
4% Sales Tax
Step-by-step explanation:
$14 is the original total and the total including tax is $14.56 meaning the tax is $.56
$.56 fits int o $14 25 times 14/.56=25
100%=$14 $.56=100%/25=4%
Meaning the Sales tax is 4%
Company a = 22 + 0.07m
company b = 8 + 0.12m
We are looking for the time when the prices are equal. i.e. the price of company a = the price of company b
company a = company b
22 + 0.07m = 8 + 0.12m
22 - 8 = 0.12m - 0.07m
14 = 0.05m
m = 14/0.05
m = 280
Therefore, the two companies will cost the same if you talk for 280 minutes

69=3x
69 ÷3 is 23
x+1=24
x+2=25
