Answer: $23.04
Explanation: 18 x 0.28 = 5.04
$18 + $5.04 = $23.04
x+y = 652
x-3y=0
need to enter those into a graphing calculator to get the answers
x=489 ( games)
y=163 ( system)
them check 163*3 = 489 and 489+163 = 652
Answer:
Denise, and by $1.60
Step-by-step explanation:
Ok so Jane bought 3 sheets of poster board and a pack of markers. You would multiply the amount of an item by its cost. So it would be 3 times $1.29, which is $3.87. For the markers she only bought 1 pack so it’s 4.50, and just add $1.29 with $3.87. For Denise, she bought two packs of construction paper and a tube of glue. Now the same as the one before, you multiply the amount of an item by its cost. For the construction paper, it would be 2 times $3.79 which is $7.58. For the glue you only bought 1 so it’s $2.39. Add those two values up. Now you will compare them. Jane spent $8.37 and Denise spent $9.97. We know now that Denise spent more than Jane. For the second part of the question how much more? We basically just subtract the two values. $9.97-$8.37 which is $1.60. There you go, hope this helps.
