3) Multiply the price of the item ($40) by the percent of the sales tax (8%). Then add that to the price of the item to get the total.
=$40 * 8%
=40 * 0.08
=$3.20 tax
=$40 price of item + $3.20 tax
=$43.20 total
5) Multiply the number of students in the band last year (36) by the percentage increased (125%).
=36 * 125%
=36 * 1.25
=45
Hope this helps! :)

Answer: 29.3
Step-by-step explanation:
Abby's average after taking 31 quizzes is 76.
Total test scores= 31 × 76 = 2356
After Abby's teacher drops her 3 lowest test scores, her average increases to 81. This means that (31-3)= 28 test scores were used.
Total scores = 28 × 81 = 2268
Sum of Abby's three lowest score
= 2356 - 2268
= 88
Average of the three scores will now be 88 divided by 3
= 88/3
= 29.3
The average is 29.3
Answer:
Step-by-step explanation:
The point is located in Quadrant II of the graph, where x-values are negative and y-values are positive.
Each marking on the graph represents one unit of distance. The two <em>axes</em> meet at the origin, where the coordinate point is equal to .
So, you can count backwards once from the origin to get your x-value ⇒ and count up upwards four times from to get your y-value ⇒ .
Finally, place these in a coordinate point ⇒ .
