Inequality:
She can afford to buy the lunch and bus rides
Step-by-step explanation:
Given
daily
daily
Solving (a) The inequality
Let bus ride be represented with B and Lunch be represented with L
If 1 bus ride costs $1.75, then
B bus ride would cost $1.75 * B
If 1 lunch costs $3.00, then
L lunch would cost $3.00 * L
Total Spending is then the sum of the above expression i.e.
$3.00 * L + $1.75 * B
The question says Camille can not spend more than $50.00.
This is represented by less than or equal to.
So, the expression is:
Solving (b): Can she afford 7 lunch and 14 bus ride?
To do this, we simply substitute 7 for L and 14 for B
The above inequality is true.
<em>Hence, she can afford to buy the lunch and bus rides</em>
