$147.50 ($250.00x.05=$12.50)x 10= $125.00
($250.00x.03=$7.50)x 3= $. 22.50
Answer:10(6)
Step-by-step explanation: add them together? not 100% sure tho
The general term is obtained by starting with the initial value 5 and then subtracting 4 each time you wish to generate a new term:
a2 = second term = 5+(2-1)(-4) = 5+(-4) = 1
General term:
an = nth term = 5+(n-1)(-4)
Thus, the 21st term is 5+(21-1)(-4) = 5 + (20)(-4) = -75 (answer)
now, we're making the assumption that the front and back of the tent are trapezoidal, Check the picture below.
