Answer: 60 cappuccinos were sold.
Explanation:
x = number of lattes sold
y = number of cappuccinos sold
Two equations can be set up:
x + y = 78
4x + 3y = 252
The first equation can be rearranged and substituted into the other equation to find the value of a variable.
y = 78 - x
4x + 3(78 - x) = 252
4x + 234 - 3x = 252
x + 234 = 252
x = 18
To find y, the value of x can be substituted into either equation.
x + y = 78
18 + y = 78
y = 60
To check answers, substitute both values into the original equations and make sure they work.
x + y = 78
18 + 60 = 78
78 = 78
4x + 3y = 252
4(18) + 3(60) = 252
72 + 180 = 252
252 = 252
We are going to define two equations where b means bagels and m will be muffins, First equation: 10*b + 4*m = 13 Second equation: 5*b + 8*m = 14 From the second equation, we can isolate b: b = (14 - 8*m)/5 In the second equation 10*(14 - 8*m)/5 + 4*m = 13 2*(14 - 8*m) + 4*m = 13 28 - 16*m + 4*m = 13 28 -13 = 16*m - 4*m 15 = 12*m m = 15/12 = 1.25 Then b = (14 - 8*m)/5 = (14 - 8*1.25)/5 = 4/5 = 0.8 So one bagel costs $0.8 and one muffin $1.25
I think that would be $11 a day because $44 divided by 4 days is $11 a day.
9 / 5/8 =
9/1 / 5/8 =
9/1 * 8/5 = 72/5 = 14 2/5
