First you would have to find the cost for 1 medium pizza.
10.50/3=3.5
It costs $3.50 for 1 medium pizza
Next, you would have to multiply 3.5 times 10.
3.5*10=35
It costs $35.00 for 10 medium pizza's.
Answer:
the answers are 12.5, 5, 2, 0.8 and 0.32
Step-by-step explanation:
2(0.4)^-2
=2(6.25)
= 12.5
2(0.4)^-1
= 2(2.5)
=5
2(0.4)^0
=2(1)
=2
2(0.4)^1
=2(0.4)
=0.8
2(0.4)^2
=2(0.16)
=0.32
