Lyle bought 3/8 pound of red grapes and 5/12 of green grapes. how many pounds of grapes did he buy ?

it's equivalent, so we can say that its equal.

let's call the denominator x and the numerador is 18 less then denominator, x - 18.

multiply

2.x = 5.(x - 18)

2x = 5x - 90

90 = 5x - 2x

90 = 3x

x = 90/3

x = 30

so:

the final price would be 29.6925

step-by-step explanation:

39.59 minus 25% equals 29.6925
