Answer 1

Answer:

Step-by-step explanation:Normal price of the phone is 910...And it's on sale for 25 percent off

Interpretation of that; 910 * 25/100 =227.5

So 227.5 is off the normal price

Meaning ; 910 minus 227.5= 682.5

He needs 682.5 to buy the phone.

He earn $9.90 = 1 hour

So, 140 hours earn him $9.90 × 140 =1386

But since he planned to save only 1/2 of his earning for the phone

Meaning 1386 × 1/2= 693

He's gonna be able to save $693 for the 140 hours of work for the phone

$693 is more than $682.5 which is needed to purchase the phone after working 140 hours

I.e Nathan will be able to purchase the phone after working 140 hours.
