The number of days that Jim can rent the car for is 4 days.
Word problems in Linear equations.
Linear equations involving word problems requires translating the word problems and representing it in the linear form y = mx + b. The variables here are not raised to the power of exponent.
From the given information:
The cost for the miles driven will be = 0.10 × 250
The inequality can be represented as:
T = 21d + 0.10(250)
where;
- T = Total cost
- d = number of days
However, since he has 115 to spend. It implies that we can express this as an inequality:
21d + 0.10(250) ≤ 115
21d + 25 ≤ 115
21d ≤ 90
d ≤ 90/21
d ≤ 4.3
Therefore, the inequality is 21d + 25 ≤ 115 and the approximate number of days that Jim can rent the car for is 4 days.
