I-PHONE that costs $289,
will he have to work 20,
25, or 30 hours? Write and
solve an equation then
Explain your answer.

Answer 1

Answer:

25 HOURS

Step-by-step explanation:

12.35(x) ≥ 289

12.35(20) ≥ 289

247≥289 NO FOR 20

12.35(25) ≥ 289

308.75≥289  YES FOR 25 HOURS

Answer 2

Answer:

y = 23.4 hrs

Step-by-step explanation:

y$12.35 = $289

y = hours he’ll to work

$12.35 = amount earned per hour

$289 = cost of the iPhone

Therefore

y12.35 = 289

Divide both sides by 12.35

y12.35/12.35 = 289/12.35

y = 23.4

y = 23.4 hrs

Fredrick will have to work for 23.4 hrs to get $289 for the phone

Check

23.4 x 12.35 = 288.99

= 289
