A.) Polly bought a cracker for $4 and then bought a parrot for $3. By how much did Polly's account change after her transactions?

Step-by-step explanation:

Word problem which can be modeled by the addition of two negative numbers :

A.) Polly bought a cracker for $4 and then bought a parrot for $3. By how much did Polly's account change after her transactions

Amount spent on cracker = - $4

Amount spent on carrot = - $3

Change in account = - 4 + (-3) = - $7

B.) Marcus sold a cat for $9 and then bought a plant for $4. By how much did Marcus's account changed after his transactions?

Amount received from sale of cat = $9

Amount spent on plant = - $4

Change in account = 9 + (-4) = $5

C.) Virginia sold her pottery for $5 and then sold a hat for $2. By how much did Virginia's account change after her transactions?

Amount received from sale of pottery = $9

Amount received from sale of hat = $2

Change in account = 9 + 2 = $11

D.) Amir bought a VCR for $8 and then resold it for $9. By how much did Amir's account change after his transactions?

Amount spent on VCR = - $8

Amount received from sale of VCR = $9

Change in account = - 8 + 9 = $1
