Margo can purchase tile at a store for $0.89 per tile and rent a tile saw for $36. At another store she can
borrow the tile saw for free if she buys tiles there for $1.29 per tile. How many tiles must she buy for the
cost to be the same at both stores?

90

Step-by-step explanation:

1. Start by making functions for the numbers

2. You can plug in these functions into a graph to figure out the x variable

3. To check if your x is right, plug it back into the two equations

i think the correct option is the second option.

c. 27 units.

step-by-step explanation:

we are told that in circle a, ∠bae ≅ ∠dae.

we can see from our given diagram that in and ;

, as these are radii of our given circle.

therefore, by sas congruence postulate.

hence, side be will be equal to side de as corresponding parts of congruent triangles are congruent. so we can set an equation to find the value of x as:

now let us substitute x=17 in the expression for the length of be.

therefore, length of be will be 27 units and option c is the correct choice.
