multiply 4.7 pounds times $ 3.80
4.7 x 3.80 = 17.86
Subtract 17.86 from 20.00
20.00 - 17.86 = 2.14
Alonzo will recieve $ 2.14

Multiply 4.7 by $3.80 which gives you $17.86 then subtract that by $20.00 and you have change of $2.14
Hope this Helps!

translation tip:
"at $3.80 a pound" means
cost (of 1 pound) = $3.80
Basic formula:
Cost of N pounds = N * (cost of 1 pound)
cost of (4.7) pounds
= (4.7) * (cost of 1 pound)
= 4.7 * ($3.80)
= $17.86
Change = (money given to clerk) - (cost of 4.7 pounds)
= ($20) - ($17.86)
= $2.14

1lb = $3.80
4.7lb * ( $3.80 / 1lb ) = $17.86
$20.00 - $17.86 = $2.14
