Sebastián was saving $8.50 each week in order to have enough money for a phone that costs $122. If his father started him off with $25, write an inequality that can be used to determine the minimum number of whole weeks, w, Sebastián will need to save.

Step-by-step explanation:

122 - 25

97

y= 8.5x + 25

97/8.50 <

11.4 --> 12

x < 12

25 + 8.50w ≥ 122

Step-by-step explanation:

Given that:

Amount saved per week = $8.50

Cost of phone = $122

Starting amount = $25

Minimum Number of whole weeks (w) Sébastien will need to save :

Starting amount + (weekly saving * number of weeks) ≥ 122

25 + 8.50w ≥ 122

8.50w ≥ 122 - 25

8.50w ≥ 97

w ≥ 97/8.50

w ≥ 11.4117

Number of whole weeks = 12

its the second choice.

step-by-step explanation:

the elements in the range will be 7 less than the elements in the domain.

answer: they are supplementary angles

step-by-step explanation: 161+19=180. supplementary angles equal 180 degrees
