I purchased a notebook for $3.50 and a pack of pencils for $ 2.50. If the sales tax was 7%, what is the total cost of my purchases? *

Respuesta :

Answer:

6.42 dollar

Step-by-step explanation:

(3.5+2.5)x0.07+(3.5+2.5)

=(3.5+2.5)x(1+0.07)

6.42
3.50 + 2.50 x 7% = 6.42or
3.50 + 2.50 x 0.07 = 6.42
