Answer:

$3.62 per gallon

Step-by-step explanation:

let initial price per gallon be [tex]P_g[/tex].

[tex]P_g=$23.79/7.1g\\=$3.35/g[/tex]

Price per gallon is raised by 8%. The new price will therefore be calculated as:

[tex]P_g_n_e_w=P_g_o_l_d\times (100+8)\%\\=3.35\times1.08\\=$3.62[/tex]

Hence the new price per gallon is $3.62
