Martin will earn $350 for 28 hours of work.
Step-by-step explanation:
Given,
Amount earned in 7 hours = $87.50
Ratio of time to amount earned = 7:87.50
Let,
x be the amount earned in 28 hours.
Ratio of time to amount earned = 28:x
Using proportion;
Ratio of time to amount earned :: Ratio of time to amount earned
Product of mean = Product of extreme
Dividing both sides by 7
Martin will earn $350 for 28 hours of work.

<h3><em>Further explanation </em></h3>
The derivative magnitude is a quantity derived from the principal amount
7 main quantities have been determined based on international standards, namely:
Newton (N) is one unit of force (F) which is a quantity derived from mass (m), length (l) and time (s)
Newton can be expressed in terms of Kg m / s²
Formula used:
F = m. a
N = kg. m / s²
In the British system there are units of slug, feet, and pounds so that the unit of force becomes:
F = m. a
Lb = slug. ft / s²
The relationship between the two-unit systems above is:
1 kg = 0.0685 slug
1 slug = 14.59 kg
1 newton = 0.225 lb
1 lb = 4,448 newtons
1 ft = 0.3048 m
So if we change 15 N to lb by using slug and ft
15 N = 15 * (1 / 14.59) slug * (1 / 0.3048) ft / s²
15 N = 3,375 slug ft / s ²
15 N = 3,375 lb
or we convert directly:
15 N = 15 * 0.225 lb
15 N = 3,375 lb
