Santi bought a dozen glasses at a price of Rp. 17,000 per glass. Then he bought 19 more glasses at a price of Rp34,000 per glass. How much money do you have to pay for the glasses?
Answers
Settlement:
One dozen glasses = 12 glasses
The money that must be paid is as follows.
⇒ 12 × 17,000 + 19 × 34,000
⇒ 12 × 17,000 + 19 × 2 × 17,000
⇒ 17,000 × (12 + 19 × 2)
⇒ 17,000 × (12 + 38)
⇒ 17,000 × 50
⇒ 850,000
Thus, the amount of money that must be paid by Santi is Rp.850,000.
