A cake and three icecream cost $ 210. Mary bought a cake and two icecream for $200. What is the cost of one icecream
Let's assume the cost of the cake is "C" and the cost of one ice cream is "I".
From the given information, we know that:
1 cake + 3 ice creams = $210,
So, C + 3I = $210.
Mary bought 1 cake and 2 ice creams for $200,
So, C + 2I = $200.
Now, we have a system of equations:
C + 3I = $210,
C + 2I = $200.
We can solve this system of equations to find the values of C and I.
To eliminate C, we can subtract the second equation from the first equation:
(C + 3I) - (C + 2I) = $210 - $200,
C + 3I - C - 2I = $10,
I = $10.
Therefore, the cost of one ice cream is $10.
The cost of one icecream is $10.
Well, it seems like Mary got a pretty sweet deal on her cake and ice cream!
Let's do a little math. If a cake and three ice creams cost $210, and Mary bought a cake and two ice creams for $200, we can subtract the cost of the cake from $200 to get the total cost of the ice creams.
$200 - (cost of the cake) = (cost of the two ice creams)
Now we know that the cost of the cake and three ice creams is $210, so we can set up an equation:
(cost of the cake) + 3 x (cost of one ice cream) = $210
Substituting the values we already have:
(cost of the cake) + 3 x (cost of one ice cream) = $210
(cost of the cake) + 3 x (cost of one ice cream) = $210
(cost of the cake) + 3 x (cost of one ice cream) = $210
Since we already know that the cost of the cake is $200, we can plug it into the equation:
$200 + 3 x (cost of one ice cream) = $210
Now we can solve for the cost of one ice cream:
3 x (cost of one ice cream) = $210 - $200
3 x (cost of one ice cream) = $10
(cost of one ice cream) = $10 / 3
So, the cost of one ice cream is approximately $3.33. Now go treat yourself to a good scoop of humor!
To find the cost of one ice cream, we first need to find the cost of the cake.
Let's assign variables to the unknowns:
Let's say the cost of the cake is C, and the cost of one ice cream is I.
From the given information, we know that a cake and three ice creams cost $210, so we can write the equation:
C + 3I = 210 ----(1)
We are also told that Mary bought a cake and two ice creams for $200, so we can write a second equation:
C + 2I = 200 ----(2)
Now, we can solve these two equations simultaneously to find the values of C (cost of the cake) and I (cost of one ice cream).
To eliminate C, we can subtract equation (2) from equation (1):
(C + 3I) - (C + 2I) = 210 - 200
C + 3I - C - 2I = 10
I = 10
Therefore, the cost of one ice cream is $10.
