If Jeff has 5 grasshoppers, then he would have 15 crickets because x(grasshoppers)+10=y(crickets), and y(crickets)+5=z(ladybugs), which would leave Jeff with 20 ladybugs.
The answer is D. Because 5 more change means that his lunch has to cost $14 or less
Answer:
x = 14.4
Step-by-step explanation:
Similar means that the figures are proportional to each other. Because of this, we can form a problem. 
(the short side lengths) = 
(the long side lengths). Now we can solve this by cross-multiplying. If we multiply 9 · 8 we get 72, and 5 · x is 5x. 72 = 5x. Now divide both sides by 5. 72 ÷ 5 = 14.4. Therefore, x should be equal to 14.4. Does this make sense?
