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.
