Math exercise 1

A store has a sale on all their merchendise. on the whole week they sell for 69000$. 45% on all their merchendise there are 20% discount. The rest of the merchendise were there 50% discount.

How much money would the store have earned if they didnt have a discount the whole week?

Svar:

20% rabat på 45% af solgte vare: 69000 * 0,45 * 0,20 = 6210

50% rabat på 55% af solgte vare: 69000 *0,55 * 0,50 = 18975

samlet tab på varerne pga. af udsalg: 6210 + 18975 = 25185

den normale udsalgspris uden rabat ville have været: 25185 + 69000 = 94185
