Dave has $11 to spend on an $8 book and two birthday cards (c) for his friends. How much can he spend on each card if he buys the same card for each friend? WHAT IS THE INEQUALITY

Dave has $11 and he buys a book for $8 but he spends an equal amount of money on 2 cards. Let's model this problem with an inequality.

x = $ spent on one card.

2x + $8 ≤ $11

Let's subtract $8 from both sides.

2x ≤ $3

Divide both sides by 2

x ≤ $1.5

Dave can spend at most $1.5 on each card.

answer:   35 % is the probability of a late departure or an early arrival.

step-by-step explanation:

let l represents the late departure and e represents the early departure.

then, according to the question,

p(l) = 12 %,   p(e) = 27 % and = 4 %

and, we have to find out,

but, we know that,

which is the required equation that will use to find the probability of a late departure or an early departure.

therefore,   the probability of a late departure or an early arrival =   35 %
