Explanation Given Information: 2 tires of each size are bought at sale. The provided table is, Tire Size Original price Sale price 14 in. $36 $32 15 in $40 $34 Formula used: Steps for multiplying whole numbers: Step 1: Write down the factors such that the place values line up in columns. Step 2: Multiply every digit of the multiplier with the multiplicand, starting with the units. Each multiplication gives a partial product whose unit digit appears under the same column that is the corresponding digit of the multiplier. Step 3: Now in each column, add the digits of the partial products, starting with the unit’s column on the right. Steps for adding whole number, Step 1: Line up the place values by writing the whole numbers in column- units, tens, hundreds, thousands, and so on. Step 2: Starting from the right with the unit’s column, add the digits in each column. Step 3: Write the units digit and carry the tens digit to the top of the next column to the left, when the total in column is greater than 9. Steps for subtracting whole number, Step 1: Line up the place values by writing the whole numbers in column- units, tens, hundreds, thousands, and so on. Step 2: Starting from the right with the unit’s column, subtract the digits in each column. Step 3: A digit must be borrowed from the column to the left of the working column, if the column cannot be subtracted. Calculation: Consider the provided data, Tire Size Original price Sale price 14 in. $36 $32 15 in $40 $34 Sale price: The price of 2-14 in. tires in sale will be, 32 × 2 ¯ Multiply the multiplier ‘2’ with the multiplicand. 32 × 2 64 ¯ Therefore, price of 2-14 in. tire in sale is $64. The price of 2-15 in. tires in sale will be, 34 × 2 ¯ Multiply the multiplier ‘2’ with the multiplicand. 34 × 2 68 ¯ Therefore, price of 2-15 in. tire in sale is $68. Total price of all the tires in sale will be, 68 + 64 ¯ Consider the operation, and line up the place values: 68 + 64 ¯ Now, add the digits in each column starting from the right with the unit’s column: 68 + 64 ¯ As the sum of the column is greater than 9 then, unit digit is written and tens digit will be carried to the top: 1 68 + 64 2 ¯ Now, proceed further similarly, 1 68 + 64 132 ¯ Therefore, total price of all the tires in sale is $132
