And I is throwing money at birthday party. She has $100 to spend. She buys a cake for $30, a giant balloon for $20, and 10 cups that each cost the same price. Create and solve any equation to determine the cost of each cup.

Step-by-step explanation:

Step one:

given data

total amount = $100

cost of cake=$30

cost of balloon=$20

let the cost of 1 cup be x

so cost of ten cups = 10x

Step two:

The expression for the total amount is given as

100=30+20+10x

100=50+10

100-50=10x

50=10x

divide both sides by 10

x=50/10

x=$5

the cost of one cup is $5

the cost of ten cups is 5*10= $50

answer rather than having to add and subtract the measurements of the semi-circle, notice that the semicircle to the left of ad is actually identical in area to the blank semicircle-shaped space to the left of bc. so if we transferred the red semicircle into the blank space, we would end up with a square of side length 24 cm. the area of a square is s^2 = 24^2 = 676 cm^2.

u also answered this so i think u would know but i am here to

put in or use mine
