3.1 The learners sell 340 vetkoek for 15 weeks. They charge R12.00 for each vetkoek.
Calculate the profit they will make if the cost for each vetkoek is R4.00 and the
costs of all ingredients is R623.48 per week.​

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.
