Allison works for a computer software company. she earns \$225$225dollar sign, 225 per week plus \$25$25dollar sign, 25 for each software package that she sells that week. if she wants to earn at least \$400$400dollar sign, 400 this week, what is the minimum number of software packages that she must sell this week?

7 software packages

Step-by-step explanation:

Given,

Signing amount = $ 225,

Additional amount for each software package = $ 25

Thus, the total amount for x software packages = signing amount + additional amount for x packages

= 225 + 25x

If total amount ≥ $ 400

225 + 25x ≥ 400

25x ≥ 400 - 225

25x ≥ 175

Hence, the minimum number of software packages that she must sell would be 7.
