Matematiske opgaver: procent, funktioner, geometri og sandsynlighed

1.1) Hvor mange penge går til nødhjælp, hvis eleverne sælger 500 pakker med

julekort?

They get DKK 40 per Christmas card but DKK 27.50 of the DKK 40 per card goes to

emergency aid. So if the students sell 500 of them, you just have to multiply DKK 27.50 by

500

27,50 × 500 = 13750.

Svar: 13750 kr

1.2) Hvor mange procent af prisen for en pakke julekort går til nødhjælp?

You have to multiply the total price they get for a Christmas card (DKK 40) by 2.5 to get it to

100 because then it is easier to calculate percentages. Then you have to multiply what goes

to emergency aid (DKK 27.50) by 2.5, which then becomes 68.75, which is then the

percentage that goes to emergency aid.

40 × 2,5 = 100

svar: 68,75 %

27,50 × 2,5 = 68,75

1.3) Tegn en graf, der viser sammenhængen mellem det antal pakker, eleverne

sælger, og det beløb, som går til nødhjælp.

In the graph, y = 27.50 X is written, which means that for each card that is sold, the

emergency aid receives DKK 27.50

1.4) Hvor stort et bidrag vil virksomheden give, hvis eleverne sælger 750
