A market stall charges $5 for 4 avocados and $10 for 10 avocados. Assume that there is a linear relationship between the number of avocados and the cost.
(a) State the equation relating the cost of the avocados and number of
avocados.
(b) At this rate, how much should the owner of the market stall charge for 6
avocados?

where are the options?

step-by-step explanation:

an = 22 + (n-1) *6

110 seats

step-by-step explanation:

an=a1+(n-1)(d)

a1 = 22   this is the first item in the sequence

d =6   this is how the sequence goes up

a)   an = 22 + (n-1) *6

b) a12 = 22 + (12-1) *6

    a12 = 22+11*6

  a12 = 22 +88

  a12 = 110
