Answer:
C 44.59
Step-by-step explanation:
The first two shirts are full price
2*49.96 = 99.92
The third shirt is 50% off. That means it is 50% of the original price
.5*49.96 = 24.98
The total cost before tax is
99.92+24.98 =124.90
tax = cost * tax rate
tax = 124.90*.071
tax=8.87
Add this to the cost
final cost = 124.90+8.87
=133.77
We want to find the mean cost (average cost)
Take the total cost and divide by the number of shirts
133.77/3 =44.59
Answer:
20 liters of the 40% solution
60-20=40 liters of the 70% solution
Step-by-step explanation:
40%x+70%(60-x)=60%(60)
0.4x+0.7(60-x)=0.6(60)
0.4x+42-0.7x=36
-0.3x+42=36
-0.3x=-42+36
-0.3x=-6
0.3x=6
3x=60
x=60/3
x=20 liters of the 40% solution
60-20=40 liters of the 70% solution
check: 0.4*20=8
0.7*40=28
8+28=36 and 0.6*60=36 also
Answer:
They lost a total of -12 yards.
