Answer:
she has $78.5
Explanation:
1- She has 5 rolls of pennies containing 50 coins each.
Total pennies she has = 5*50 = 250 pennies
Now, we will get the amount of pennies she has in dollars as follows:
1 penny ............> 0.01 dollar
250 pennies .....> ??
Amount is dollars = 250*0.01 = $2.5 .............> I
2- She has 3 rolls of nickels containing 40 coins each
Total nickels = 3*40 = 120 nickels
Now, we will get the amount of nickels she has in dollars as follows:
1 nickel ..............> 0.05 dollar
120 nickels .........> ??
Amount in dollars = 120*0.05 = $6 ............> II
3- She has 6 rolls of dimes containing 50 coins each
Total dimes = 6*50 = 300 dimes
Now, we will get the amount of dimes she has in dollars as follows:
1 dime ...........> 0.1 dollar
300 dimes .....> ??
Amount in dollars = $30 ...............> III
4- She has 4 rolls of quarters containing 40 coins each.
Total quarters = 4*40 = 160 quarters
Now, we will get the amount of quarters she has in dollars as follows:
1 quarter ...........> 0.25 dollar
160 quarters ........> ??
Amount in dollars = $40 ..........> IV
5- Final step:
we will add I,II,III and IV to get the total amount of money she has as follows:
Total amount of money = 2.5 + 6 + 30 + 40
Total amount of money = $78.5

Answer is 152.68 simple subtraction problem
Step-by-step explanation:
Hey there!
The equation of a line which passes through the point (1,1) is <em>(y-1) = m1 (x-1)...............(i)</em> {using one point formula}
Also, another equation which is perpendicular to the line is <em>y = 1/5 x + 4/5..........(ii)</em>
Comparing equation (ii) with y= mx+c, we get;
Slope (m2) = 1/5.
Now, As per the condition of perpendicular lines,
m1*m2 = -1
or, m1 * 1/2 = -1
or, m1= -2
Therefore, m1 = -2.
Keeping the value of m1 in equation (i) we get;
y-1 = -2(x-1)
y-1 = -2x+1
or, y+2x-2= 0
Therefore, the required equation is 2x+y-2= 0.
Hope it helps!
