Answer:6.48
Step-by-step explanation:
1.60 times 4 jus to start it off it will be 6.40 plus the 1/2 pound it will be .80 plus 6.40 will be 7.20 and 10 percent off that is .72 the remainder will be 6.48
A. The answer is 6$ because 3 x 2 is 6
B. The answer is 12
a₅ = 10
a₁₀ = 20
a₁₅ = x
-------------------------------------------------------------------------------------------------------------------
Note that from a₅ to a₁₀, there is a addition of 10. This means that for every x(₅) jump, you add 10 to the whole number.
-------------------------------------------------------------------------------------------------------------------
So in this case:
a₁₀ = 20
a₁₅ = x
a₁₀ (+₅) = 20 (+10)
a₁₅ = 20 + 10
a₁₅ = 30
Note that: a₁₅ = x = 30
-------------------------------------------------------------------------------------------------------------------
x = 30, or (A) is your answer
