Answer: He spend $36 in all and $9 for tax and tip.
Step-by-step explanation:
Since we have given that
Amount of bill for dinner = $45
Rate of tax = 5%
Rate of tip = 15%
Amount of tax would be
[tex]0.05\times 45\\\\=\$2.25[/tex]
Amount of tip would be
[tex]0.15\times 45\\\\=\$6.75[/tex]
total amount he spend for tax and tip combined is given by
[tex]2.25+6.75\\\\=\$9.00[/tex]
Amount he spend in all is given by
[tex]\$45-\$9\\\\=\$36[/tex]
Hence, he spend $36 in all and $9 for tax and tip.
