Complete question :
Taylor earns $5 each time she walks her neighbor's dog. She has already earned $25. Write and solve an equation to find out how many more times Taylor needs to walk the dog to earn enough to buy a bike that costs $83.
Answer:
12
Step-by-step explanation:
Amount earned for walking dog = $5 per walk
Amount already earned = $25
How many more times dog needs to be walked to buy a bike which costs $83
Target amount = 83
(Target amount - already earned amount) / amount earned per Walk
(83 - 25) / 5
58 / 5
= 11.6
Hence, Taylor needs to walk her neighbor's dog 12 more times
Answer:
Four (4) pounds
Step-by-step explanation:
Because we required two (2) pounds to stretch the spring eight (8) inches, we need double the force to stretch it sixteen (16) inches. Sixteen is just double the original amount, meaning we need four (4) pounds to stretch the spring sixteen inches.
