A pencil costs $3.50 and a pen costs $6.70. Jessica bought m pens. She also bought 4 fewer pencils than pens. Write and algebraic expression for the total amount she spent.

Jessica bought X pens, which cost $6.70 each.

She also bought 4 fewer pencils than pens, or (X-4) pencils, at $3.50 each.

So in total, she spent:

6.7X + 3.5(X-4)

= 6.7X + 3.5X - 14

= 10.2X -14

So she spent $(10X - 14) on pens and pencils.

Step-by-step explanation:

Ok so Jessica bought M pens, which cost $6.70 each.

She also bought 4 fewer pencils than pens, or (M-4) pencils, at $3.50 each.

So in total, she spent:

6.7M + 3.5(M-4)

= 6.7M + 3.5M - 14

= 10.2M -14

So she spent $(10M - 14) on pens and pencils.

Hope this helped :)

x > 1.3

step by step:

8.5−0.9x> 9.8−1.9x

step 1: simplify both sides of the inequality.

−0.9x+8.5> −1.9x+9.8

step 2: add 1.9x to both sides.

−0.9x+8.5+1.9x> −1.9x+9.8+1.9x

1x+8.5> 9.8

step 3: subtract 8.5 from both sides.

1x+8.5−8.5> 9.8−8.5

1x> 1.3

step 4: divide both sides by 1.

1x/1 > 1.3/1
