Karla bought a student discount card The card cost $6 and allows her to buy each meal for $3 after one week Karla spent $15 how many meals did she buy ?

3 meals

Step-by-step explanation:

The card costs $6, so we will subtract that from $15 because it is the starting amount. Karla can't buy these meals for $3 without $6. Anyways, 15-6 is 9. Each meal costs $3 so we'll then divide 9 by 3, which gives us our she bought 3 meals.

Karla bought 3 meals.

Step-by-step explanation:

6+3m=15

Subtract 6 both sides.

3m=9

Divide 3 both sides.

m=3

m=meals she bought

answer: solve 5\cdot 2^x=2405⋅2  

x

=2405, dot, 2, start superscript, x, end superscript, equals, 240.

solution

to solve for xxx, we must first isolate the exponential part. to do this, divide both sides by 555 as shown below. we do not multiply the 555 and the 222 as this goes against the order of operations!

\begin{aligned} 5\cdot 2^x& =240 2^x& =48 \\ \end{aligned}  

5⋅2
