Can i have help on this please ^^ Suppose you are organizing a party and have a budget of b dollars for the appetizers. You plan to order v vegetarian spring rolls at $0.75 each and s shrimp rolls at $0.95 each. The equation 0.75v + 0.95s = b represents this constraint. When might it be most handy to use each of these equations in your party planning?
0.75v + 095s = b

v= (b-0.95s)/0.75

s= (b-0.75v)/0.95

The answer would be v = b/0.75 - 0.95s/0.75 or it would be  

v = (b - 0.95s) / 0.75

Step-by-step explanation:  

 You would solve 0.75v + 0.95s = b for v

which  means making v the subject of the formula

0.75v + 0.95s = b

Then you would subtract 0.95s from both sides

0.75v + 0.95s - 0.95s = b - 0.95s

0.75v = b - 0.95s

Divide both sides by 0.75

v = (b - 0.95s) / 0.75

v = b/0.75 - 0.95s/0.75

Therefor the  equation will be useful in determining the number of vegetarian. Hope it helps you!

answer: i think it is (1,-2)
