Agrocery store has 12 lb of trail mix that is 10% banana chips. the store's manager would like to add banana chips to bring the new mix up to 25% banana chips. write and solve a system of equations to find out how many pounds of banana chips manager needs to add.

10% of the 12 lb mix is banana chips, which comes out to 1.2 lb of banana chips. If is the amount of banana chips the manager will add to the mix, then the new mix's total weight would be , and the manager wants 25% of this to consist of banana chips. This means the final amount of banana chips, , should come out to 25% of . In other words,

so the manager should add 2.4 lb of banana chips.

y = 5x + 17

step-by-step explanation:

a perpendicular line will be the opposite reciprocal slope of the given equation.   the slope given is -1/5 so the opposite reciprocal is 5

find b:

7 = 5 (-2) + b

7 = -10 + b

17 = b

write equation

y = 5x + 17
