Answer:

There were 210 downloads of the standard version.

Step-by-step explanation:

This question can be solved using a system of equations.

I am going to say that:

x is the number of downloads of the standard version.

y is the number of downloads of the high-quality version.

The size of the standard version is 2.6 megabytes (MB). The size of the high-quality version is 4.2 MB. The total size downloaded for the two versions was 4074 MB.

This means that:

$2.6x + 4.2y = 4074$

Yesterday, the high-quality version was downloaded four times as often as the standard version.

This means that $y = 4x$

How many downloads of the standard version were there?

This is x.

$2.6x + 4.2y = 4074$

Since $y = 4x$

$2.6x + 4.2*4x = 4074$

$19.4x = 4074$

$x = \frac{4074}{19.4}$

$x = 210$

There were 210 downloads of the standard version.
