Let c represent candy and s soda.
2c+s=8
c+s=5.5
Solving the pair of simultaneous equations by eliminating s,
c=2.5
Representing the value of c in equation 1;
5+s=8
s=3
So, a box of Candy costs 2.5 and a soda costs 3
Answer:
2/9
Step-by-step explanation:
28 marbles in all
"Half of the marbles are red."
28/2 = 14 red
"Half of the non-red marbles are white..."
14/2 = 7 white
"...and the rest are blue."
25 -14 -7 = 7 blue
"Todd chose a <u>white marble</u> at random... " -from the bag that has...
14 red 7 white 7 blue
"... and <u>kept it</u>."- so now the marbles left in the jar are...
14 red 6 white 7 blue
P (white) = Number of white marbles/ Total number of marbles = 6/27 = 2/9
Answer: Elisa
Step-by-step explanation:
Elisa withdrew $20 at a time from her bank account and withdrew a total of $160. The number of times she made a withdrawal will be:
= $160 / $20
= 8 times
Frances withdrew $49 at a time from his bank account and withdrew a total of $196. The number of times she made a withdrawal will be:
= $196 / $49
= 4 times.
From the calculations above, we can see that Elisa made the greater number of withdrawals.
