Valeria already has $65 dollars in her savings account. If she puts $5 per week in her account, write and solve an inequality to find out how many weeks she must save to have at least $200 in her account.
Answers
Answer:
65 + 5x ≥200
Step-by-step explanation:
Hi, to answer this question we have to write an inequality with the information given:
Janice's savings (65) plus the product of the amount she saves per week (5) and the number of weeks (x) must be higher or equal to $200.
Mathematically speaking:
65 + 5x ≥200
If we solve it for x:
5x ≥200-65
5x ≥135
x ≥ 135/5
x ≥ 27 weeks
