Question

Laurie and Maya sold at most $50 worth of get-well and friendship cards. The friendship cards, x, were sold for $2 each and the get-well cards, y, were sold for $1.50 each. Which point represents a reasonable number of cards sold?

Answer 1

The point is (15,10)

Explanation:

Given data:

cost of card $50

x card sold for $2

y card sold for $1.50

from the above information given above we have following relation

2x + 1.50y = 50

the above equation is linear, therefore to find the point to point out the number of card sold, hit and try method should be used. select the proper point (x, y) so that after putting in above equation there result must not be greater than 50

Try for (15,10)

`2 * 15 + 1.50* 10  \geq 50`

`45 \geq 50`
