To determine the correct error in the pet store owner's calculation regarding the payments for the snake costing $288, we can analyze the situation mathematically.
The total amount Samuel needs to pay is $288 and he is supposed to make 6 equal payments. To find the amount of each payment, we can divide the total cost by the number of payments:
\[ \text{Payment amount} = \frac{288}{6} \]
Doing the division:
\[ 288 \div 6 = 48 \]
This means each of the 6 payments should be $48.
Given that the pet store owner suggested 6 equal payments of $49, let's calculate the total amount that would result from these payments:
\[ 49 \times 6 = 294 \]
This total of $294 is greater than the snake's price of $288, indicating that the $49 payment is incorrect.
Thus, the correct conclusion is:
There is a multiplication error. The payment should be $48 per month.
