Tammy decorated her art project with 12 different colors of sequins if she used 15 of each color how many sequins did tammy use

We are given that:

Tammy used 12 different colors of sequins

Tammy used 15 sequin of each color.

Therefore, to get the total number of sequins that she used, we will multiply the number of colors by the number of sequins of each color as follows:

Total number of sequins = 12*15 = 180 sequins
