Help me i need to do question 1 (e,f,g,h) and question 2 (e,f,g,h)

Пошаговое объяснение:

Question 1

e) $350 by 20% = $350 + 0,2 * $350 = $350 + $70 = $420

f) $750 by 35% = $750 + 0,35 * $750 = $750 + $262,5 = $1012,5

g) 900 g by 40% = 900 g + 0,4 * 900 g = 900 g + 360 g = 1260 g

h) 50 min by 20% = 50 min + 0,2 * 50 min = 50 min + 10 min = 60 min = 1 hour

Question 2

e) $930 by 10% = $930 - 0,1 * $930 = $930 - $93 = $837

f) $6354 by 20% = $6354 - 0,2 * $6354 = $6354 - $1270,8 = $5083,2

g) $134 by 25% = $134 - 0,25 * $134 = $134 - $33,5 = $100,5

h) $575 by 30% = $575 - 0,3 * $575 = $575 - $172,5 = $402,5
