Answer:
$8.99
Step-by-step explanation:
1 pound = 16 ounces
y pound = 8 ounces
y · 16 = 1 · 8
16y = 8
16y ÷ 16 = 8 ÷ 16
y = 0.5
0.5 pound = 8 ounces
----------------------------------
1 pound = $17.98
0.5 pound = y
y · 1 = 17.98 · 0.5
y = $8.99
Which applies the power of a power rule to simplify the expression
