A cell phone plan costs $21.70 per month for 500 minutes of talk time. It costs an additional $0.06 per minute for each minute over 500 minutes. To get e-mail access, it costs 30% of the price for 500 minutes of talk time. Your bill, which includes e-mail, is the same each month for 6 months. The total cost for all 6 months is $196.26. Write and solve an equation to find the number of minutes of talk time you use each month.

You use 487 minutes of talk time each month.

question 1: step-by-step explanation:

1/4 of 84 = 84÷4= 21

step-by-step explanation:

hihi so drawing these 2 triangles is fairly simple. all that's left is finding the height of each one. luckily, we have a side length and an angle, so there is a trig function we can use to solve for the height. the easiest one to use would be tangent, since we have 2/3 things needed to find and the third needed is what we are solving for. tan(73°) * 30 ~= 98.13 and tan(73°) * 35 ~= 114.45
