Question

a local grocery stand sold $12,456.98 on a friday. there were 2 customers. circle the expression that would provide the best estimate for the average amount spent by a customer. $13,000 ÷ 300 $12,000 ÷ 300 $10,000 ÷ 300 $12,000 ÷ 200 mr jackson took his new car on a family vacation. he drove the car 1,454.625 miles and used 4.5 tanks of gas. how many miles does he get on a single tank of gas?

Explanation:

Step1: Find average amount per - customer

To estimate the average amount spent by a customer, we divide the total amount by the number of customers. We need to round the total amount and number of customers for estimation. The total amount is $12,456.98$ and assume 300 customers (since the options have 300 as the divisor in most cases). Rounding $12,456.98$ to the nearest thousand gives $12,000$. So the best - estimating expression is $\$12,000\div300$.

Step2: Calculate miles per tank

To find the number of miles per single tank of gas, we divide the total number of miles driven by the number of tanks of gas used. The total miles driven is $1454.625$ and the number of tanks is $4.5$. So the calculation is $1454.625\div4.5 = 323.25$ miles per tank.

Answer:

The best expression for the average amount spent by a customer is $\$12,000\div300$.
He gets 323.25 miles on a single tank of gas.
