Question #317077

Write a system of equations to describe the situation below, solve using substitution, and fill in the blanks.


Aunt Nellie is pricing cakes for a baby shower she is throwing. She wants one large cake shaped like a duckling and also some cupcakes in pastel colors. Lowell Bakery charges $4 for each cupcake, plus $38 for the large cake. Gabby's Sweet Shoppe charges $60 for the large cake and $2 for each cupcake. If Aunt Nellie orders a certain number of cupcakes, the cost will be the same at either bakery. What would the total cost be? How many cupcakes would that include?

Let xx be the number of cupcakes.

Then


38+4×x=60+2×x38+4x=60+2x38+4\times x=60+2 \times x\\ 38+4x=60+2x

since the cost will be the same at either bakery.


Solving the equation we get


4x2x=60382x=22    x=114x-2x=60-38\\ 2x=22 \implies x = 11

Thus, the number of cupcakes is 11.


The total cost is:

$60+$2×11=$60+$22=$82\$ 60 + \$ 2 \times 11 = \$ 60 + \$ 2 2 =\$82\\
