rodikova [14]

Answer:

a) marked-down price = $6.00

b) with-tax cost = $6.06

Step-by-step explanation:

0.20 × $7.50 = $1.50

so the marked-down price is ...

$7.50 - 1.50 = $6.00

b) The sales tax is ...

0.01 × $6.00 = $0.06

so the total cost with tax is ...

$6.00 + 0.06 = $6.06

Of course, you know that 20% = 20/100 = 0.20, and 1% = 1/100 = 0.01.
