Answer:
c)
Step-by-step explanation:
create a system of equations:
d + m = 104
2d + 3m = 243
now use substitution method based on 'd = 104 - m'
2(104 - m) + 3m = 243
208 - 2m + 3m = 243
208 + m = 243
m = 35
So, 35 muffins and 69 donuts were sold.
This is 34 more donuts than muffins.

Step-by-step explanation:
Answer:
Eight times ten plus six times one plus two times one-tenth plus seven times one-thousandth.
Step-by-step explanation:
(8 x 10) = eight times ten
(6 x 1) = six times one
(2 x 0.1) = two times one-tenth
(7 x 0.001) = seven times one-thousandth
I am not always the best with the equations to words stuff, so please comment if I am wrong!
Based on the numbers we have we can assume that she saves 3 times more each week than the last (1*3=3, 3*3=9).
Following this trend we would multiply the amount she saved the third week ($9) by 3 to get $27 for the fourth week.
Then, we would multiply the amount she saved the fourth week ($27) by 3 to get $81 for the fifth week.
Finally, to figure out how much she saved in the 5 weeks, we need to add each value up to get 1+3+9+27+81= $121 saved in 5 weeks
1. (1.35)x(.42)
1.35
x. .42
________
270
5400
________
.5670
You need to have the total number of decimal places from the original two numbers. 1.35 has two decimal places and .42 has to decimal places you have a total of four decimal places, Which means 5670 is .5670
2. (.22)x(.04)
.22
x. .04
_______
88
00
_______
.0088
you need to have the total number of decimal places from the original Two numbers. So .22 is two decimal places and .04 is two decimal places, so you will need to have for decimal places. That means that the answer 88 needs to be translated into .0088
