Seven huge boxes and two tiny boxes total were bought by the contractor.
A linear equation is defined as an algebraic equation of maximum degree 1 is a linear equation.
According to the question, a builder needs to purchase nails to construct a house.
Both small and large boxes of nails are provided. There are 50 nails in each small box and 350 in each large box.
The contractor purchased 5 more large than tiny boxes, hence it is assumed that he purchased a certain number of little boxes.
He purchased (x+5) huge cartons.
So, 50(x) + 350(x+5) = 2590.
50x + 350x + 1750 = 2590.
400x = 2590 - 1750.
400x = 840.
x = 2.1
The bulk of the boxes he bought is 7.

Answer:
The equation can be used to determine the amount of money S(t) that her savings account has after t years is 
Step-by-step explanation:
A student invests $500 in a savings account
Principal = $500
Rate of interest = 4% = 0.04
We are supposed to find equation can be used to determine the amount of money S(t) that her savings account has after t years
Formula : 
Where A is the amount after t years =S(t)
t = time
r = rate of interest in decimals =0.04
P = Principal=500
Substitute the value in the formula :
So, 

Hence The equation can be used to determine the amount of money S(t) that her savings account has after t years is
