Can someone answer this question please please answer it correctly and please show work please help me I need it

Answers are below

Step-by-step explanation:

48) Expression for Shipping charges for Supplier 1 is S = 16x + 0.05

      Expression for Shipping Charges for Supplier 2 is S = 18x + 0.07

      Expression for Total Cost for Supplier 1 is C = (16x + 0.05)0.9

      Expression for Total Cost for Supplier 2 is C = (18x + 0.07)0.8

If he ordered 15 T-shirts from each supplier, you need to use the second set of expressions.

Supplier 1 - (16(15) + 0.05)0.9 = (240 + 0.05)0.9 = (240.05)0.9 = $216.05

Supplier 2 - (18(15) + 0.07)0.8 = (270 + 0.07)0.8 = (270.07)0.8 = $216.06

In total the coach spent 216.05 + 216.06 = $432.11 for both suppliers

36) D because surveying the 85 people means that they are unbiased on their favorite sport. The 15 people were all on the soccer team, so they would pick soccer.

37) C because 2/3 cups times 1.5 would equal one cup. Now multiply the 3/4 pound of blueberries by 1.5.       3/4 x 1.5 = 1.125 = 1 1/8

38) A because a 25% chance of snow is a low chance of snow. If the percent was over 50%, then there would be a high chance.

34) D because both are ways of finding the discounted price, but Michael's way is preferred because there are less steps involved.

35) C because it is the middle number and it shows the average speed during the trials.

area of part 1:

a1=base*height/2=(8+2)*(8-2-2-1)/2=10*3/2=15 ft^2

area of part 2:

a2=length*width=(8+2)*1=10 ft2

area of part 3:

a3=length*width=8*2=16 ft2

total shaded area : a1+a2+a3=41 ft2

total area of the reactangle : a=16*8=128 ft2

total area of the nonshaded region : 128-41=87 ft2
