none of these are correct unless it's a trick question I'm not getting.

She payed $19.91 for the bananas and grapes

Step-by-step explanation:

The expression for the total amount she payed for the bananas and grapes is as follows;

T = (B*N1) + (G*N2)

where;

T=total amount payed

B=cost per pound of banana

N1=amount in pounds of the banana

G=cost per pound of grapes

N2=amount in pounds of the grapes

In our case;

T=unknown

B=$0.49 per pound of banana

N1=35 pounds of the banana

G=$1.15 per pound of grapes

N2=2.4 pounds of the grapes

T = (0.49*35) + (1.15*2.4)

T = (17.15+2.76) = $19.91

She payed $19.91 for the bananas and grapes
