1. Which is an example of a linear equation correctly written in standard form?
a. -4x + 5y = 22
b. 3x + 1/2y = 10
c. 7x - 9y = 14
d. 3/4x + 6y = -25

the correct answer is you spend $55.78 more in a brand store that buy ing in a normal store.

step-by-step explanation:

brand = spend   $ 135.85 total
