. Irwin bought a shirt for $35, socks for $15, and sneakers for $120. How much will he pay in total, including an 8.875% sales tax?

Respuesta :

35 + 15 + 120 = 170

170 x 1.08875 = 185.0875

= $185.09

(multiplying by this number because 1.0 refers to 100% so the whole 170 = 1, 200% of 170 would be x2 because there’s two lots of 170 etc. 0.088… refers to the 8..% because you’re adding that on.)

> not sure if that explanation makes a lot of sense but just wanted to add it just in case
