JEWELRY Ava bought a necklace for $8.50 and some earrings
that cost $3.75 for each pair. The total cost was $19.75. Write
and solve an equation to find how many pairs of earrings
Ava bought

Respuesta :

1 necklace = $8.50
1 pair of earrings = $3.75

8.50+3.75 = 12.25
19.75 - 12.25 = 7.5

7.5 / 3.75 = 2

in total ava bought 3 pairs of earrings
$19.75 - $8.50 = $11.25/$3.75 = 3 pairs of earrings
