To find out how many of each type of calculator was ordered, we can set up a system of equations based on the given information.
Let's assume the number of calculators that cost $57 each is x, and the number of calculators that cost $57 is y.
From the given information, we know that the total number of calculators ordered is 51. So our first equation is:
x + y = 51
We also know that the total cost of the order was $1941. The calculators that cost $57 each would have a total cost of 57x, and the calculators that cost $57 would have a total cost of $57 multiplied by the number of calculators, which is y. So our second equation is:
57x + 57y = 1941
Now we have a system of equations:
x + y = 51 --(1)
57x + 57y = 1941 --(2)
To solve this system of equations, we can use the method of substitution or elimination.
Let's use the method of substitution:
Solve equation (1) for x:
x = 51 - y
Substitute this value of x into equation (2):
57(51 - y) + 57y = 1941
Now we can solve for y:
2907 - 57y + 57y = 1941
2907 = 1941
Since 2907 does not equal 1941, this equation is not true. Therefore, there must have been a mistake in the given information or calculations.
Please double-check the information provided to ensure its accuracy.
