2^{5x + 3} = 3^{2x + 1}
log_{2}(2^{5x + 3}) = log_{2}(3^{2x + 1})
(5x + 3)log_{2}(2) = (2x + 1)log_{2}(3)
5x + 3 = 1.58(2x + 1)
5x + 3 = 3.16x + 1.58
1.84x + 3 = 1.58
1.84x = -1.42
x \approx -0.77

Doss [256]

Answer:

$22.84

Step-by-step explanation:

The tax is calculated by 0.075 * 21.25 = 1.59375 or $1.59. So the total bill is the cost of items purchased plus tax, which is $21.25 + $1.59 = $22.84.
