Jenna's parents have given her an running shoes. interest-free loan of $100 to buy a new pair of she plans to pay back the loan with monthly $20 each a. write a function rule for the balance function b(p), where p represents the number of payments that jenna has made. b. after how many payments will jenna have paid back more than half the loan? explain your reasoning. c. suppose the loan amount were $120 and the monthly payments were $15. write a rule for the new balance function and use it to determine how long it would take jenna to pay off the loan.

answer: its the third option.

step-by-step explanation:

i just took the test.

answer:

given the linear inequality :

add 2y to both sides we get;

simplify:

add 12 to both sides of an equation;

simplify:

divide both sides by 2 we get;

or

the related equation for the inequality equation [1] is;

y-intercepts defined as the graph crosses the y-axis.

substitute x =0 in [2] to solve for y;

y = 6

x-intercepts defined as the graph crosses the x-axis.

substitute value y = 0 to solve for x;

subtract 6 from both sides we get

multiply both sides by 2 we get;

or

x = -12

now, plot these point (0, 6) and (-12, 0) on graph as shown below and shade the graph below the solid line.
