Sara goes to a furniture store to buy a dining set, end tables, and a loveseat. She sees a lamp for $40 and an end table for $62
BaLLatris [955]

Answer:

$1191.60

Step-by-step explanation:

<u>Option 1:</u>

Leather Loveseat

1200 plus 2% extra charge and NO TAX

What is 2% of 1200??

0.02 * 1200 = 24

So total price = 1200 + 24 = $1224

<u>Option 2:</u>

Lush Blue Loveseat and Lamp

Lush Blue loveseat is 980 + 17% tax, that would be worth 980 + (0.17)(980) = $1146.6

and

lamp is worth 40 with 12.5% tax, that would be worth 40 + (0.125)(40) = $45

Total cost = 1146.6 + 45 = $1191.6

2nd option is cheaper, so that would cost $1191.60

35. A can of popcorn is to be packed in a box for shipping as shown. The can is 18 inches tall and has a radius of 7 inches. The
lianna [129]

The amount of packing material is 1506 cubic inches

<h3>How to determine the amount of packing material?</h3>

The given parameters are:

<u>Can</u>

Radius, r = 7 inches

Height, h = 18 inches

<u>Box</u>

Base dimension, l = 15 inches

Height, h = 19 inches

The volume of the can is:

V = \pi r^2h

So, we have:

V_1 = 3.14 * 7^2 * 18

V_1 = 2769

The volume of the box is

V =l^2h

So, we have:

V_2 =15^2 * 19

V_2 =4275

The amount of packing material is;

Amount = V2 - V1

This gives

Amount = 4275 - 2769

Evaluate

Amount = 1506

Hence, the amount of packing material is 1506 cubic inches

in a survey, 27% of people chose salads over a meat dish. In all, 81 people chose salads. How many people were in the survey?
adelina 88 [10]
Number of people that chose salad = 81
Percentage of people that chose salad over meat dish = 27%
Let us assume the number of people on the survey = x
Then
27% * x = 81
(27/100) * x = 81
27x = 81 * 100
27x = 8100
x = 8100/27
   = 300
So a total of 300 people participated in the survey.I hope the procedure is clear enough for you to understand. Based on this method you can always solve similar types of problems without requiring any kind of help from outside.
