If Ping buys a sandwich and bottle of juice at that price , his total would be $7.70 in a world without tax. So 10.00-7.70 and his change would be $2.30 :)
But without plugging this into a calculator round the numbers up , $6+$2=$8 leaving him with approximately $2 in change.

You did this correctly :) I'm proud

Yes, u did it correctly.

estimate : 10 - (6 + 2) = 10 - 8 = 2
exact : 10 - (5.95 + 1.75) = 10 - 7.70 = 2.30

Mashutka [201]

Answer:

40% students play the saxophone.

Step-by-step explanation:

Given:

Total Number of students who play woodwind instrument = 45

Number of students who play saxophone = 18

We need to find the percent of students who play saxophone.

Solution:

Now we can say that;

To find the percent of students who play saxophone we will divide Number of students who play saxophone by Total Number of students who play woodwind instrument and the multiply by 100.

framing in equation form we get;

percent of students who play saxophone = $\frac{18}{45}\times100= 40\%$
