Answer:
72÷6=12
so at the nursery it cost $12 per shrub
66÷6=11
so at the store it cost $11 per shrub
so if you buy 21 shrubs from the nursery it will cost: 12×21=$252
but if you buy 21 shrubs from the store it only cost: 11×21=$231
$252-$231=$21

Answer:
The answer is $1.25
Step-by-step explanation:
She buys 4 notebooks for $2.50 dollars each.
Multiply 2.50 times 4 then you get $10.00
She buys pencils 10 for $0.75 each.
Multiply 10 times 0.75 and you will get $7.50
Then you add $10.00 + $7.50 which will give you $17.50.
Subtract $17.50 from $23.75 which will give you $6.25.
You divide $6.25 by 5 which will give you $1.25.
