Answer:
t = 1.025c + 5.99
Step-by-step explanation:
Recall : general for of a linear equation is given by :
y = mx + c
Given the following :
Item cost = c
Shipping charge = $5.99
Tax on purchases = 2.5%
Total cost, t
t = c + tax + shipping cost
Tax on purchase : 2.5% * item cost ; 0.025c
Shipping = $5.99
Hence,
Total cost, t = c + 0.025c + 5.99
t = 1.025c + 5.99

Answer:
x= -3
Step-by-step explanation:
7 + 2x/3 = 5
Subtract 7 from both sides,
2x/3 = 5-7

2x = -2*3
Divide by 2,
x = -2*3 / 2
x = -3
