Question

Help please! Giving medal.

Answer 1

rate per ounces = difference in rate/ difference inounces
r = 1.34 - 1.17/ 2.00 -1.00
r = 0.17 per ounces
a = 1.17 - 0.17 = 1.00
as we can see through table, its an arithmetic progression
\[a_n = a + (n-1) * d\]
an = cost of 11 ounces
n = 11
d = 0.17
an= 1.00 + (11-1) * 0.17
an = 1.00 + (10*0.17)
an = 1.00 + 1.7
an = $2.70

Answer 2

thank you so much!

Answer 3

are you sure it's not 1.00 + (11*0.17)?
