After a 15% discount, the price reduced to

`\Rightarrow \text{Reduced Price}=20* -20* 0.15\\\Rightarrow \text{Reduced Price}=20[1-0.15]=20* 0.85\\\Rightarrow \text{Reduced Price}=\$17`

After this, a sales tax is applied

So, there would be an increase in price

`\Rightarrow \text{New Price}=17+17* 0.07\\\Rightarrow \text{New Price}=17[1+0.07]=17* 1.07\\\Rightarrow \text{New Price}=\$18.19`

So, the father pays an amount of
`\$18.19`
