Problema Solution
If the tax that you pay when you purchase an item is 12% of the sale price! write an expression that gives the tax on the item with a price p. Write another expression that gives the total price of the item, including tax.
Answer provided by our tutors
Let 'T' represents the tax then the expression that gives the tax on the item with a price p is:
T = (0.12)p
Let 't' represents the total price of the item including tax then:
Total price equals the tax plus the regular price.
t = T + p
t = (0.12)p + p
t = p(0.12 + 1)
t = 1.12p is the expression that gives the total price of the item, including tax.
