Answer:
$4.59
Step-by-step explanation:
At the sale price:
5 paints set cost Jasmine $16.45
Each paint set = Total cost of 5 paints set / 5
= $16.45 / 5
= $3.29
What was the price of 1 paint set before the sale?
Because the store reduces the price of each paint set by $1.30 before selling, we will add $1.30 to the price of each paint set during sales
Price of each paint set during sales = $3.29
price of 1 paint set before the sale = $3.29 + $1.30
= $4. 59
Nora's speed (5*8)m²/2h= 20 m²/h.
Zack's speed (4*9)m²/3h= 12 m²/h
Together for 1 h they paint (20+12) m²/h=32m²/h
Given area (10*12)m²=120 m²
120m² *1h/32m² = 3.75 h (3h 45 min) to paint 10m*12m together.
