Answer: 
Step-by-step explanation:
Given: The sales of 10000 increased by 65% each year .
Let x be the number of years.
The rate of growth=65%= 0.65
The exponential growth function is given by
, where A is initial amount and r is the rate of growth in decimal.
Then the increase in the sales id given by :-
Use the slope-intercept form to find the slope and y-intercept.
Slope:
3

y-intercept:
(
0

)
perimeter is 2L+2W
problem states width = 5L+13
so plug that in for w:
P=2L+2(5L+13)
now simplify
P=2L+10L+26
P=12L+26
All we need to do is to find out how many 25 cm cake tins will fit along the 70 cm edge (70 cm because 700 mm = 70 cm).
70 : 25 = 2,8
It means that 2 and 0,8 tins will fit, which is generally 2 tins because the third one wouldn't fit.
Now we have to do the same with the 60 cm edge:
60 : 25 = 2,4
So again we'll have 2 tins along the other edge, but with less spare space.
Now we just have to multiply both edges to get the amount of the tins that will fit on the tray:
2 * 2 = 4
Answer: 4 cake tins will fit on oven tray measuring 700mm x 600mm.
