I need help please!!!! Jon buys t shirts online for his friends. the table below shows the cost including the shipping fee. writ
Ronch [10]
A t-shirt costs $12 per t-shirt plus $3 shipping. Write the equation that describes the total cost c for the number of t-shirts purchase t.

so equation
c = 3 + 12t

if t = 1 then c(cost) = 3 + 12(1) = 3 + 12 = 15
if t = 2 then c(cost) = 3 + 12(2) = 3 + 24 = 27
if t = 3 then c(cost) = 3 + 12(3) = 3 + 36 = 39
if t = 4 then c(cost) = 3 + 12(4) = 3 + 48 = 51

Find an equation of a line through (2, 1) and perpendicular to −2x + 4y = 8
MAVERICK [17]

Hello:<span>
the equation is : y = ax+b
the slope is a : a×(1/2) = -1......( perpendicular to a line with a slope of   1/2)            because :    -2x+4y =8...y=(1/2)x+2    )     </span>

<span>
a = -2       y=(-2x+b
the line that passes through (2,1) :1 = -2(2)+b
b =5
<span> the equation is :  y  = -2x+5</span></span>
