Number of apples purchased = A
Cost of each apple = 15 cents
Then
The total cost of 15 apples = 15A
Number of bananas purchased = B
Cost of each banana = 10 cents
Then
Cost of 10 bananas = 10B
So
The total value of purchase = 15A + 10B
So the correct option among all the options given in the question is option "D",. I hope the procedure is clear enough for you to understand. Using this procedure it will be possible for you to answer similar questions with ease and without requiring any help from outside.
Answer:
2 x+3 y and 3 x+ 2 y
Step-by-step explanation:
Let x represents the number of roast beef and y represents the number of turkey sandwiches.
Let r and t represent cost of the roast beef and sandwich.
Platter A:
Platter A has 2 roast beef and 3 turkey sandwiches. So, equation is 2 x+3 y.
Total cost of the platter = 2 r x+3 t y
Platter B:
Platter B has 3 roast beef and 2 turkey sandwiches. So, equation is 3 x+2 y.
Total cost of the platter = 3 r x+2 t y
So, the two equations are 2 x+3 y and 3 x+ 2 y.
Answer:
I think you just plug in the first equation to the or the second to the first, it’s actually does not matter. After that you just solve it. For example: we have two equations.
y=11-2x
y=x+2
We just plug in the first equation to the second one.
11-2x=x+2
-3x=9
x=-3. So this is the answer. Hope this helps.
