Question

Can y’all solve it using geogebra something like that

Answer 1

The first 10 pounds is $2 per pound so $2 x 10 = $20

She wants to pick 40 pounds so after the first 10 pounds she needs 40-10 = 30 more pounds.

The cost for those are $1 per pound so 30 x $1 = $30

Total cost = $20 + $30 = $50 for 40 pounds.
