Answer:
B
Step-by-step explanation:
.4 as we know can also be handled as .40, as the zero helps us determine the difference in value. 50%, though it is a percentage, can be put into decimal form. That would be .5, or again, we could add a zero to help us out, which would make it .50. As of right now, .4 is less than 50%. 3 and 13 are whole numbers, so they do not really need deep observation, except that 3 is less than 13. That would make the order of number from least to greatest .4, 50%, 3, and 13.
Answer:
1 toast costs $0.30 and 1 egg cost $0.60
Step-by-step explanation:
Let price of 1 egg be
and price of 1 toast be 
<u>"$1.50 for 2 eggs and one piece of toast":</u>
We can write 
<u>"$.90 for one egg and one piece of toast":</u>
We can write 
Now, we can solve the first equation for t and substitute that into 2nd equation and solve for e:

Now using the value of e (0.6) and putting it back in the first equation, we will get t:

Hence, 1 toast costs $0.30 and 1 egg cost $0.60
Answer:

You have 2 apples.
You can get this by subtracting the 3 from the 5 you originally had.
Expenses: $6.00 + $4.50 + $2.50 = $13.00
income = balance + expenses
income = $3.52 + $13.00
income = $16.52
