Chelsea wants to buy a new iPhone that costs $324. She has already saved $56. If she can save $20 a week, how
many weeks will it take for her to be able to purchase the
iPhone?

14 full weeks.

Step-by-step explanation:

The phone costs $324 and she saved $56, so we subtract $56 from $324.

$324 - $56 = $268

She saves $20 each week so we divide $268 by $20 to get the number of weeks.

$268/20 = 13.4

It will take 13.4 weeks, but we have to round up because at 13 weeks she won't have enough saved. So 14 full weeks.

costs the what? what is the cost of the pants?

step-by-step explanation:

if it is $10, then the price is 14.

take 40% of the cost, and then add the cost.

40% of 10 = 4

4+10 = 14.
