Yunika downloaded four applications for $2.99 each to her cell phone. The remaining applications that Yunika purchased cost $1.9
9 each.If she downloaded x total applications, which of the following equations can be used to find how much Yunika spent on cell phone application downloads? A. y = 1.99(x - 4) + 11.96
B. y = 11.96(x - 4) + 1.99
C. y = 1.99x + 11.96
D. y = 11.96x + 1.99
The answer would be C. She bought four applications for 2.99 each. you would multiply 2.99 x 4 to get 11.96. X would be the variable and we don’t know how many apps she bought for 1.99 so we would do 1.99 by however many apps she bought and 11.96 of the four apps she bought to find the total. this gets the answer of y = 1.99x + 11.96
Let N be the length of the real house. To solve, write the equation in ratio - 2/4 = N/17 2(17) = 4(N) 34/4 = 4N/4 N = 8.5 Therefore, the length of the real house is 8.5
