Ian is buying bagels for a family gathering. Each bagel costs $1.75. Answer the questions below regarding the relationship between the total cost and the number of bagels purchased.
The independent variable, x, represents the number of bagels purchased, and the dependent variable is the total cost of the bagels, because the number of bagels purchased depends on the total cost of the bagels.
A function relating these variables is H(x)= blank*.
So H(18)= blank*, meaning 18
-bagels will cost
-dollars is the price for
blank*
-dollars
-bagels
.
H(x) = 1.75x
So H(18) = 1.75*18 = 31.50
Therefore, 18 bagels will cost $31.50.
