Answer:
y=3.11x
Step-by-step explanation:
Not sure if it's correct. But my reasoning behind it is that 23.81-20.70=3.11 which means every year the cost goes up by $3.11
To find the cost of each item, you will create an equation in terms of the t-shirt.
Each item is related to the price of the t-shirt.
SWEATPANTS + SWEATSHIRT + TEE SHIRT = TOTAL COST
(2t - 5.50) + (t + 8) + t = $76.50
4t + 2.50 = 76.50
- 2.50 -2.50
<u>4t</u> = <u>74</u>
4 4
t = $18.50
The tee shirt is $18.50.
The sweatpants are 2 x $18.50 - 5.5 = $31.50
The sweatshirt is $18.50 + 8 = $26.50
