The answer is 9.48. also I rounded
Using the distributive property we know we distribute by multiplying the outside values to those inside of the parentheses
outside values: 2
inside values: 5 and r
now multiply out inside values by the outside values
2x5 = 10
2xr = 2r
now plug these values back in for the inside values and take away the outside value and the parentheses
so 2(5+r) using the distribution property is 10+2r
Answer:
regular price = $15
Step-by-step explanation:
Represent the regular price by d. Then the discount was 0.20d, and the sale price was (1 - 0.20)d, or 0.80d, which is $12.
Solving for d, we divide both sides by 0.80:
d = regular price = $15
