B. carlos monthly office supply budget is $250. he needs to buy ink cartridges which cost $40 a piece. he will need to save at least $50 of his budget for reams of paper. what is the range of ink cartridges he can buy and still have enough money left over for the reams of paper?

ANSWER

Find out the what is the range of ink cartridges he can buy and still have enough money left over for the reams of paper.

To proof

let us assume that the number of the ink cartridges buy be x.

As given

Carlos monthly office supply budget is $250.

He needs to buy ink cartridges which cost $40 a piece.

He will need to save at least $50 of his budget for reams of paper.

than the inequality is written in the form

x ≤ 5

the range of the  ink cartridges he can buy  be 0 ≤ x ≤ 5 when he saves

at least $50 of his budget for reams of paper.

Hence proved

answer: d. $20

step-by-step explanation:

just took the test

answer: (c) m∠qpo + (2x + 16)° = 180°

step-by-step explanation:

the opposite angles of a quadrilateral are supplementary.

so, ∠o + ∠q = 180°   and   ∠p + ∠r = 180°

since ∠r = 2x + 16°, we can use substitution as follows:

∠p + ∠r = 180°

∠p + (2x + 16)° = 180°
