4. Each month for 2 months, Kyle buys a pack of 8 replacement tires for his remote-control car. At the end of each month, he has 1 tire left. Explain how the numerical expression for the number of tires Kyle uses in 2 months compares to the numerical expression for the number of tires he uses in 1 month.

Respuesta :

Each month Kyler buys a pack of 8 replacement tires.

He does this for 2 months.

At the end of each month he has 1 tire left.

So the numerical expression for the number of tires he uses per month will be;

Number of tires used in 1st month = 8-1 =7

Number of tires used in the 2nd month = 8 - 1= 7

Total number of tires used in two months = 7*2 = 14

Tires left in two months = 1+ 1 = 2

Comparison : The number of tires used in two months is twice that used in one month.
