Answer:
Man has 9 Nickels and 7 dimes.
Step-by-step explanation:
Let Number of dimes be x
and Number of Nickels be y
As Per given data he has two more nickels than dimes.
As we know that
1 = 100 cent
1 nickel is worth = 5 cents = = 0.05
1 dime is worth = 10 cents = 0 .1
According to given data he has total nickel and dimes
So the equation becomes,
but
Substituting value of x in equation we get
Man has 9 Nickels and 7 dimes.
15 caps are needed so that she can earn $85 in an hour day.
The direct variation equation has the form y = kx, where k is the constant proportionality. It is a linear equation with two variables. In a coordinate plane, the direct variation graph is a straight line. A constant is the ratio of two quantities that vary directly. Relationship between two variables that can be described mathematically by an equation where one variable equals a constant multiplied by the other.
For each hour she is compensated $6.50 with $0.45.
For an 8 hour day =6.50 *8 + 0.45x
Let x be the caps and earning is $85
6.50*8+0.45*x=85
=> 52+0.45x=85
=> 0.45x=33
=> x=15 (approx.)
