Answer:
45 or more
Step-by-step explanation:
If x is the amount of pastries they sell, we need to multiply it by $3.00 to know how much they raise. Total earnings: $3.00x
They need to raise at least $135, that is $135 or more.
So, $3.00x has to be greater than $135 or equal.
Written as an inequality is:
$3.00x $135
We divide both sides by $3.00 and we have:
x $135/$3.00 = 45
Therefore, they need to sell 45 or more pastries to meet the goal.
C) d =rt
6.75 x 21 = 141.75
141.75 x $2 = $283.50
60 total fourth graders and 43 are girls. To find the number of boys, subtract.
60 - 43 = 17 boys
If 5 girls were absent, subtract.
43 - 5 = 38 girls present
If 4 boys were absent, subtract.
17 - 4 = 13 boys present
Therefore, there were 13 boys present.
Best of Luck!
