Answer:
6d
Step-by-step explanation:
because when you add 2+3 is six and i get the d because d is the next one of c
Answer:
Donuts cost $2.00 and Cookies cost $1.50
Step-by-step explanation:
D = cost of a donut
C = cost of a cookie
4D + 10C = $23.00
8D + 6C = $25.00
Eliminate a variable when subtracting the two equations. Change both values with C to 60 in order to eliminate the C variable and solve for D.
80D + 60C = $250.00 subtracted from 24D + 60C = $138
56D = $112.00 (Divide by 56 to single out the variable)
56D/56 = $112.00/56
D = $2.00
Use the D value to solve for C.
4(2) + 10C = $23.00
8 + 10C = $23.00
8 - 8 + 10C = $23.00 - 8
10C = $15.00
10C/10 = $15/10
C = $1.50
Check:
Bentley:
4D + 10C = $23
4(2) + 10(1.50) = $23
8 + 15 = $23
23 = 23
Skylar:
8D + 6C = $25
8(2) + 6(1.50) = $25
16 + 9 = $25
25 = 25
Answer:
Step-by-step explanation:
We are letting <em>d</em> represent the number of drinks and<em> p</em> represent the number of pizza slices.
We know that each drink <em>d</em> costs <em>$2</em>. We also know that each pizza slice <em>p</em> costs <em>$4</em>. They spent a total of $28. Therefore:
We also know that 9 items was purchased all together. So, the total number of drinks <em>d </em>and pizza slices <em>p</em> sum to 9:
Therefore, our system of equations is:
