Answer:

3p = $2.10

p = $0.70

Step-by-step explanation:

Cost of a pencil: p

Cost of a pen: p × 2 = 2p

If the cost of 1 pen and 1 pencil is $2.10,

2p + 1p = $2.10

3p = $2.10

p = $0.70

Lemur [1.5K]

Answer:

Step-by-step explanation:

Your question isn't complete but let me help out based on the information given.

Joshua's recipe for chili requires 2 3/4 ​ pounds of beef. Sondra's recipe for chili requires 2 2/3 ​ pounds of beef.

The pounds of beef required by both of them will be:

= 2 3/4 + 2 2/3

= 2 9/12 + 2 8/12

= 4 17/12

= 4 + 1 5/12

= 5 5/12

The difference in the pounds of beef required by both of them will be:

= 2 3/4 - 2 2/3

= 2 9/12 - 2 8/12

= 1/12

Also, we.can also infer that Joshua recipe for chili requires more pounds of beef than that of Sondra
