A company sells t-shirts for $6 each. They also charge a one-time processing fee of $3 per order. Jamie ordered t-shirts and paid $45 for his order. Two days later, Jamie could not recall how many t-shirts he ordered. Which shows the equation that Jamie could use to find the number of t-shirts, x, he ordered and the solution of the equation? A)6x + 3 = 45, x = 7 B)6x + 3 = 45, x = 8 C)3x + 6 = 45, x = 13 D)3x + 6 = 45, x = 17
@AZ
Hey so we need to come up with an equation
We know that he spent a total of 45 dollars so whatever our equation is something something = 45
but now we need to figure out what's on the other side so 6 dollars PER SHIRT and 3 dollars was a one time base fee
if he buys 'x' number of shirts and each shirt costs 6 dollars how would we write the cost of x shirts?
B?
why do you think B?
are you sure you solve the equation correctly?
OH WAIT i didnt read it right ;-;
i dont understand?
so let's go back to what I was saying if each shirt costs 6 dollars and we buy 'x' number of shirts how would we write that?
think of it like this with a number if the `x` is too hard each shirt costs $6 and let's say we bough 6 shirts how would we calculate the price of 6 shirts?
wouldn't it be a simple multiplication
yeah
so we could say 6* 6 when I use the number or 6 * x if we keep x as a variable?
im sorry but im confused ;-;
im not the brightest
so 'x' is just a letter that can represent any number but we multiply it to see the cost of how many 'x' shirts
and the 3 dollars is just a ONE TIME fee but the 6 dollars increases each time we buy another shirt
so what would the equation be? 6x + 3 or 3x + 6
6x + 3?
there you go!
so A?
\(\color{#0cbb34}{\text{Originally Posted by}}\) @AZ We know that he spent a total of 45 dollars so whatever our equation is something something = 45 \(\color{#0cbb34}{\text{End of Quote}}\) and remember this?
so 6x + 3 = 45
let's solve it now what is 45 - 3 =
42
now divide by 6
21
because 6x + 3 = 45 6x + 3 - 3 = 45 - 3 6x = 42 so to get x we have to divide by 6
are you sure that 42 / 6 is 21
oops its 7
i accidentally divided by 2 ;-;
that's your answer
a is da correct answer
Thank you! im so sorry for being difficult ;-;
i can help u
No problem :)
