Question

Im willing to learn pls help. The Spanish Club is ordering t-shirts online. The cost, c in dollars, of t-shirts, t, can be found using the function c=11t+27. If the club spent a total of $159.00 on this t-shirt order, how many t-shirts did the club buy?

Answer 1

you are given the equation c = 11t + 27

you are also given the value of c, which is 159

therefore, we can replace "c" with "159"

159 = 11t + 27

do you know how to solve for t?

Answer 2

-27 on both sides?

Answer 3

good, that's a good start

after we do that we get

132 = 11t

do you know what to do now?

Answer 4

divide by 1232 on each side

Answer 5

almost

Answer 6

132*

Answer 7

since we have 11 multiplied by t, we want to divide by 11 to turn "11t" into "t"

Answer 8

132 divided by 11 = 12

therefore, t = 12 and 12 is our answer

Answer 9

does that make sense?

Answer 10

yep thanks!
