If Alaska were divided into 10 equal pieces, then that means Florida would be the same size as one of those pieces. So write the equation .
This is equal to .
Now, when you divide a number by 10, the original number becomes one place value less. For instance, 2 ÷ 10 = 0.2.
We can see that 1,700,000 has 5 zeroes, so if you divide it by 10, the this means Florida is 170,000 sq km.
Hope this helped. :D

Answer:
C = 75 + 0.17x and R = 2x
2x - (75 + 0.17x) > 0
x ≥ 41
Step-by-step explanation:
The cost to make the cupcakes is a fixed $75 plus $0.17 per cupcakes made and the selling price of each cupcake is $2.00.
Part A: Now, the equation for the cost, C, for making x cupcakes is
C = 75 + 0.17x ......... (1)
Again the equation for the revenue, R, from selling x cupcakes is
R = 2x ............ (2)
Part B: So, the inequality that could be solved to find the number of cupcakes, x, that must be made and sold to make a profit is
R - C > 0
2x - (75 + 0.17x) > 0 ......... (3)
Part C: Solving inequality (3) we get
(2 - 0.17)x > 75
⇒ x > 40.98
⇒ x ≥ 41 {Since, x can not be a fraction}
