Chad washes windows after school to make some extra money. He charges $5.50 to wash each window. If the customer provides the su
pplies, Chad deducts $3.25 from the total cost. One customer paid a total of $35.25 and did provide supplies. Which equation could be used to find the number of windows, w, that Chad washed for this customer? *5.5w + 3.25 = 35.25
*5.5w - 3.25 = 35.25
*5.5w = 35.25
*5.5 - 3.25w = 35.25
The second option. The 5.5w part shows that its $5.50 times each window. The -3.25 is because he deducted 3.25 from the total. And then you have the price that he got on the other side.
Here's the work to find the windows in case you want it: 5.5w-3.25=35.25 5.5w=38.50 w=7 He washed 7 windows
The loan proceeds will be given as follows: A=P(1+r/100)^n Plugging the values we obtain n=4 months= A=1000(1+12/3*100)^1 A=$1040 hence the proceeds will be: 1040-1000=$40
