Tom and his family went to a restaurant for dinner the bill came to $80 they wanted to leave an %18 tip about how much tip should they leave? pls help

$80+18%= $94.4

Step-by-step explanation:

80:100×18= $14.4 (18% of 80)

$80+14.4 = $94.4

correct answer:

i^31 = -i

b. 6

step-by-step explanation:

we are given the table representing an exponential function.

we can see from the table that, as x is increasing, the value of y is increasing in the power of 6.

i.e. the following relation is obtained,

x = 1, y = 6

x = 2, y = 36 =

x = 3, y = 216 =

x = 4, y = 1296 =

x = 5, y = 7776 =

so, the geometric series obtained is .

thus, the common ratio is given by = = 6.

hence, the common ratio is 6.
