Mr. Montoya borrowed $11,550 from the bank to fix his roof. The bank set up the loan for 5.6% simple interest over 10 years. How much interest will he pay on the ten year loan?

Interest to be paid on the loan will be $6,468

Step-by-step explanation:

Isimple interest = Principal x Rate x Time

From the information given,

Principal = $11,550

Rate = 5.6% = 5.6/100 = 0.056

Time = 10years

Slot the values into the formula;

Interest= $11,550 x 0.056 x 10

=$6,468

Interest to be paid on the loan will be

= $6,468

x = -3

y = -18

step-by-step explanation:

to solve by substitution, substitute one variable and solve for the other. then substitute again to find the remaining variable.

x-1/3(3x-9) = -3 since y=3x-9 substittute y.

x-1/3(3x-9)=-3

x + x +3 = -3

2x+3=-3

2x+3-3= -3-3

2x=-6

x=-3

substitute again into y=3x-9

y=3(-3)-9

y=-9-9

y=-18
