The total number of nails will decrease by 14 when Willa will use 7 nails on each side.
Step-by-step explanation:
Sides of one birdhouse = 7
Nails used on each side = 9
Nails used on one birdhouse = No. of sides * Nails used for each side
Nails used on one birdhouse = 7*9 = 63 nails
If she uses 7 nails on each side, then the number of nails used on each birdhouse will be;
No. of nails = 7*7 = 49 nails
Difference = Old value - New value
Difference = 63-49 = 14
The total number of nails will decrease by 14 when Willa will use 7 nails on each side.
