Dionne can fold 175 packing boxes in 50 minutes. Elias can fold 120 packing boxes in 40 minutes. Use unit rates to find how much time it will take each person to fold 210 packing boxes. Drag the numbers to explain and show your answer.

60  minutes and 70 minutes respectively

Step-by-step explanation:

Step one:

given data

We are given that Dionne can fold 175 packing boxes in 50 minutes and

Elias can fold 120 packing boxes in 40 minutes

let us find the unit rate of each of them

For Dionne

= 175/50

=3.5 boxed per minute

For Elias

= 120/40

=3 boxed per minute

Step two:

Hence,  each person will fold 210 packing boxes in

For Dionne

= 210/3.5

=60  minutes

For Elias

= 210/3

=70  minutes

write out the polynomial, with leading coefficient 1:

y = 1 (x+2)^1 (x-7)^1 (x-5)^2
