Jamal placed two orders with an internet clothing store. The first order was 13 ties (t) and 4 pairs of suspenders (s), and totaled $487. The second order was for 6 ties and 2 pairs of suspenders, and totaled $232. The bill does not list per-term price, but all ties have the same price and all suspenders have the same price

t = $23

s= $47

Step-by-step explanation:

First order =

13t + 4s = 487

Second order

6t + 2s = 232

13t + 4s = 487 (1)

6t + 2s = 232 (2)

Multiply (2) by 2

12t + 4s = 464 (2b)

13t + 4s = 487

12t + 4s = 464

Subtract

12t - 10t = 487 - 464

t = $23

Substitute t = 23

13t + 4s = 487

13(23) + 4s = 487

299 + 4s = 487

4s = 487 -299

4s = 188

s = 188 / 4

= 47

s= $47

step-by-step explanation:

i think something is missing in your question because y-1=(x-12) would not pass through the point (-4,-3). because if you replace x by -4 your are supposed to find y=-3 which is not the case her. if you replace x by -4 you find =-15.

i assume the right equation is y-1=1/4*(x-12) because this one is passing through both your points (if you are interested to know how i found that out i can tell you).

in this equation if i replace x by -4 i find y=-3 and if i replace x by 12, i find y=1 so the line representing this equation is passing through those 2 points.

then the standard form of the equation is finding an expression of y in function of x

y-1=1/4*(x-12)

y=x/4-3+1

y=x/4-2

hope that .

do you confirm there was a mistake in the question?
