$~~~\text{Area of triangle} = \dfrac 12 \times \text{Base} \times \text{Height}\\\\\implies 10 = \dfrac 12 \times 5 \times w\\\\\implies w =\dfrac{20}5 \\\\\implies w = 4 ~cm$

Hoochie [10]

Answer:

300

Step-by-step explanation:

Day 1: $70

Day 2: $80

Total commission = day 1 × 2 + day 2 × 2

= 70 × 2 + 80×2

= 140 + 160

= 300

Total commission = 2(day 1 + days 2)

= 2(70 + 80)

= 2(150)

x = 300
