Answer key and explanations

D. $$24$
Discount amount $=0.25\times32=$8$. Sale price $=32-8=$24$.
D. $$90$
Markup amount $=0.50\times60=$30$. Selling price $=60+30=$90$.
D. $$50$
Sale price $=$ original price $\times(1-0.10)$. So $45=\text{original}\times0.90$, giving original $=45\div0.90=$50$.
D. $$100$
Selling price $=$ cost $\times(1+0.10)$. So $110=\text{cost}\times1.10$, giving cost $=110\div1.10=$100$.
D. $$21.60$
Tax $=0.08\times20=$1.60$. Final price $=20+1.60=$21.60$.
D. $$7.50$
Discount amount $=0.30\times25=$7.50$.
D. $$70$
Markup $=0.75\times40=$30$. Selling price $=40+30=$70$.
D. $$60$
Sale price $=$ original $\times0.60$. So $36=\text{original}\times0.60$, giving original $=36\div0.60=$60$.
