Tara models an addition using five red tiles and seven blue tiles. what is the final sum for this problem? a.) 12 b.) -12 c.) 2 d.) -2

we are given

number of red tiles =5

number of blue tiles =7

we know that

final sum for this problem is addition of these two types of tiles

so,

total number of tiles = number of red tiles + number of blue tiles

now, we can plug values

and we get

total number of tiles = 5+7

total number of tiles = 12

so,

the final sum for this problem is 12

so, option-AAnswer
