larry has $20 to spend at the store. he plans to purchase five items that cost $5.79, $7.63, $3.46, $2.99, and $3.65. larry estimated his total cost to make sure he has enough money for his purchases. is his estimate accurate? explain why or why not.\n$5 + $7 + $3 + $2 + $3 = $20
Answer
# Explanation:
## Step1: Calculate the actual total cost
$5.79 + 7.63+3.46 + 2.99+3.65=(5.79 + 7.63)+(3.46 + 2.99)+3.65 = 13.42+6.45 + 3.65=13.42+(6.45 + 3.65)=13.42 + 10.1=23.52$
## Step2: Compare with the estimate
The estimated cost is $5 + 7+3 + 2+3=20$. The actual cost is $23.52$. Since $23.52>20$, the estimate is not accurate.
# Answer:
No, his estimate is not accurate because the actual total cost of the five - items ($23.52$) is greater than the estimated cost ($20$).
