10. The diagram on the right shows the growth of a type of cell. nx4 It is given that on the first day, there are four cells. On the
second day, each cell produces three cells. On the following n
day, each new cell produces another three new cells. The
process of producing new cells repeats at the same rate.
(b)calculate the total number of cells on the fifth day

i would answer you're question. i'm trying to work it out but i'm not really understanding it. :(

The answer is the second answer from the image. Which is 5x-8y=$75

Step-by-step explanation:

It is that answer because it costs $5 for one cheese pizza and $8 for a pepperoni pizza, so the answer is 5x-8y=75

still confused?

Its that answer because the first one and the third one are the same, just both equations like in different ways like example 10+2 is 12 right? And 2 + 10 is still 12 so that means the second answer from the image is the answer.

Hope that helps.
